Leonardo Momento Zero Grande 2.0 Guilloche Fountain Pen Review

(Sarah Read is an author, editor, yarn artist, and pen/paper/ink addict. You can find more about her at her website and on Bluesky. And her latest book, The Atropine Tree, is now available!)

Every now and then I open a new pen and it's a favorite at first sight. The Leonardo Momento Zero Grande 2.0 Guilloche gave me instant heart-eyes when I opened the box. It looks amazing. The texture, the finish, the colors--all perfect. I liked the look of it so much that I actually got nervous, because what if the writing experience didn't live up to the looks? There was no need to worry. This is a fantastic pen.

The body of the pen is a cool-toned blue resin that is subtly etched with a geometric guilloche pattern that resembles ears of grain. Each of the different colors has its own etching pattern. This color is called "indigo," though it looks to me to be more of a slate grey-blue. There is also “Iris” which is dark blue and “Verdigris” which is a sage green. They're all gorgeous. The Indigo is the only one that comes with the ruthenium trim, and the gunmetal grey looks perfect with the moody blue tones. The clip is slim and fairly flexible, with a tiny wheel at the bottom to make the clipping process smoother. The cap and piston knob have metal bands that add a decorative reinforcement to these stress points. Speaking of points, both the top and bottom finials are gently pointed. The overall look is very Art Deco vintage elegance.

Under the twist cap, the grip section is engraved with "Leonardo Italy" and you're greeted with a clear resin ink window, so you can keep track of your ink supply. This is a piston filler pen, so the back end unscrews to move a plunger inside the pen that draws ink in through the nib from a bottle. It is my personal favorite ink filling mechanism, as they tend to hold quite a lot of ink, as this one does, but they can be more difficult to clean. There is no way to disassemble the pen for cleaning, so rinsing ink out is a matter of repeatedly filling the pen with water and releasing it till it runs clear. It takes longer and is less effective than a filling system you can take apart, but it's worth it to me for the higher ink capacity, and I don't like reassembling tiny pen pieces after cleaning. I'm always afraid I'll drop one. So, I prefer this. There's no fear of a precious nib falling down the drain.

They all come with either a Fine nib or a Flex Fine nib. Mine has the Flex Fine, because I like a bouncy writing experience. The nib has its sides cut out to create a narrow neck that flexes when pressure is applied. The flex nib also has "Leonardo elastic" engraved on it. This is very much a modern flex nib, which is to say that it's not super flexy. It can take some light pressure and provide some slight line variation, but it isn't bendy like a vintage flex pen would be. What I love about it is that I can get fine lines when writing, but it still has a softer writing experience, and often flex nibs have better ink flow. This combination is perfect for me when I want a longer writing session. Writing a whole short story in one sitting, but don't want to run out of ink or get hand fatigue? This is your pen. Well, no. This is my pen. But you can have one, too.

The Leonardo Momento Zero Grande 2.0 is available on JetPens for $289, which is perfectly fair. It's a fancy pen and it has a fancy pen price. It is, however, much nicer and more solidly built than some pens that are considerably more expensive. When it comes to measuring cost against quality, I think Leonardo is at the top of the game when it comes to mass-produced pens. All of their pens that I've used have been winners, and this is my favorite one, yet.

Leonardo Momento Zero Alga Fountain Pen Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

The Leonardo Momento Zero has been around since 2017, and I think it's safe to say it's been a hit. It's a vintage-inspired design that pays tribute to its Italian roots. On top of that, there are plenty of vibrant colorways to choose from.

I've had a chance to use the Leonardo Momento Zero Alga with silver trim recently, and there's certainly a lot to like about this pen. Let's get into it.

On the surface, the Momento Zero looks a bit like many other traditional fountain pen designs. The shape is well-balanced with both ends quickly tapering to a soft point. There's only one bit of branding on the pen, and that's a debossed Leonardo name and the unique number of the pen located on the back of the cap opposite the clip.

The clip is the same design that many of Leonardo's pens share. It's an elegant shape that compliments the pen shape, and the tip is a functional roller that makes it easy to attach and remove from fabric or other objects. There are three decorative silver bands at the base of the cap, as well as a couple of bands on the pen body that correspond to the connection points of the three pieces.

The material is acrylic resin and is shaped from a solid rod. The Alga colorway I chose is a mixture of deep and medium greens that give it an overall emerald look. It looks like the rods are made by combining many smaller square rods into one. Through turning the material into the final shape, the small rectangular pieces make the material look like it is striped and like the shape of the pen is faceted. The pen shape is definitely cylindrical, but I appreciate the optical illusion due to the unique materials. The combined color of the different greens with their mix of hues and lighter accents make this pen beautiful to me. Some of the materials are more transparent than others, which gives the pen a slightly luminescent quality.

The cap of the pen is secured with threads, and it's easy to use. The cap also comfortably posts on the back of the pen, though I don't like the balance of the pen for writing in this configuration. For me, it's the perfect balance without the cap attached.

It's a "standard" size fountain pen, so it's comfortable to hold when writing. The shape of the grip section is comfortable and provides a nice area to hold the pen regardless of your grip style.

The #6 JoWo nib is a perfect match the size of the pen, and the EF version in this pen works flawlessly. It's a fairly plain nib, but there is some decorative scroll work along with the nib size.

Moving into the pen, I was delighted to find a cartridge-converter included with the pen. The pen takes standard international short cartridges, but this converter is slightly longer than the typical international converter size. It also screws into the section so you don't have to worry about it shaking loose inside the body of the pen. At first, I thought the silver handle on the converter twist mechanism was purely decorative, but I soon discovered that this pen has a hidden feature.

Like any normal fountain pen, you unscrew the pen body from the section to get at the cartridge or converter. But, this pen also has a small blind cap at the end of the pen that unscrews from the pen body completely. When this piece is removed, it exposes about 0.25" (7mm) of the converter twist handle so you can make small adjustments without taking the pen apart. I've found that there isn't enough purchase to reliably operate the converter when filling the pen, but it's fine for a quick turn if you're trying to revive the ink flow after the pen has been sitting for a week or more. It's an intriguing feature, but I think it's more for show than for any real practicality. Still, it will definitely make it easy to clean the inside of the pen body if you ever have any internal ink accidents.

Finally, writing with this pen has been so pleasant. The shape of the grip, the length and balance of the pen, and the feel of the smooth acrylic material after it's warmed up in my hand make this is an excellent writing instrument for long writing sessions. The JoWo nib is smooth and delivers consistent, reliable ink flow. It's a fantastic pen that also has a unique design and beautiful materials. It's been at the top of my rotation lately.

Vanness carry the Momento Zero in a variety of colors — too many to list out, so be sure to browse the in-stock options to find the right colorway for you. Along with the colorway choices, you also have several nib choices from the standard EF-B sizes, but also a fun Elastic (Leonardo's name for flex nib available in EF or F) and a 1.5mm stub nib.

The normal price for the Momento Zero is $199, which I think is more than fair given the materials, build quality, and exceptional writing experience. At the time of this review, the Alga with silver trim model featured here is on sale for $159. I'm happy to recommend the pen at either price point.

Leonardo Supernova Star Light Blue Fountain Pen Review

(Jeff Abbott is a regular contributor at The Pen Addict. You can find more from Jeff online at Draft Evolution and Twitter.)

This Leonardo Supernova that I've had on my desk the last couple of weeks has really stolen the show in terms of my stationery rotation. I couldn't pass it up when I saw it online, but seeing the pen in person is even more striking.

The Leonardo Supernova is a regular edition that features a beautiful marbled acrylic that is made in Italy. The color I have is called Star Light Blue with Ruthenium Trim, but there are three other colors options as well. All four materials are gorgeous, but I'm a sucker for bright blues and turquoise with hints of green.

The swirl of color in this material is one thing, but Leonardo added a little extra character by including a sprinkle of reflective particles that subtly sparkle and twinkle under the light. The sparkle gives the acrylic just a little more depth and visual interest that makes the pen pop.

The fit and finish of this pen is fantastic, and I was impressed by how well-made it is for the price. Everything lines up perfectly and feels solid in the hand, and the dark trim complements the bright blue body beautifully. The wide band features a geometric design that looks great without drawing attention away from the acrylic. Aside from the band, there's also a small ring at the bottom of the pen and a functional clip on the cap. The clip is a sleek shape and has a wheel at the end that makes it just a little easier to clip onto things while still keeping the pen secure.

The Supernova sports a steel #6 Jowo nib with some decorative scroll work and the nib size inscribed at the base. The dark nib matches the rest of the trim on the pen and continues that delicious contrast between the dark metal and bright acrylic. The fine nib on this pen was smooth and crisp out of the box, and flows well with the couple of inks I've already tried with it.

Writing with the Supernova is fantastic due to the smooth nib and even balance of the pen body. You can post the cap on the back of the pen, but I prefer leaving it unposted since it's a full-size fountain pen. I like the balance without the cap a little better, but just know that the cap posts securely if you like to write with the additional weight. No one likes a loose cap on the back of the pen when trying to write!

Along with the pen and gift box, Leonardo include a standard cartridge converter so that you can ink the pen up with your favorite ink. I wish more pen manufacturers would do this instead of including a couple of generic black or blue ink cartridges!

From when I first saw the Leonardo Supernova on Goldspot's website, I had high expectations. At $152, it's not a cheap pen, and straddles a really interesting and competitive price point. At a minimum, it needs to perform like other amazing pens that you can buy at this price. I'm happy to say that this pen exceeds my expectations. It's a pleasure to use, and it looks so awesome on my desk. I can't help but pick it up and twirl it around under the light to admire the personality in the acrylic.

Aside from the fine nib, you have the option of extra fine, medium, broad, elastic extra fine, elastic fine, and 1.5mm stub. And good luck picking just one color out of this exceptional lineup of materials!
