Monteverde MP1 Mercury Orange Fountain Pen Review

Monteverde MP1 Mercury Orange Fountain Pen Review

When Monteverde launched their MP1 Fountain Pen earlier this year, I was intrigued. I like the style, and it lands in a price bracket that could make it an option for users looking for their second fountain pen. You know, the one when you decide that “Yes, I like this stuff!” and you want more from your next choice.

The Monteverde MP1 Mercury Orange Fountain Pen is a Goldspot exclusive release, and a perfect fit for the season. They sent it over to me pre-launch, and I’ve had some time to spend with it recently. So far, it has been a fantastic writer, although there is a minor change I’d like to see updated if there is a version two.

Monteverde MP1 Mercury Orange Fountain Pen Ink

Packaged with a 15ml bottle of matching Mercury Orange ink. These sets are a limited edition of 300.

For starters, the MP1 is my aesthetic: Clear barrel, color anodized cap and piston knob, complimentary gold-plated hardware. This is a common barrel layout and design, and one I find myself using in other models frequently. The Mercury Orange aluminum that Goldspot chose for their pen pops off the desk, and in my hand.

Monteverde MP1 Mercury Orange Fountain Pen Piston

The locking piston, pulled out. The two white dots line up for closure.

The piston mechanism has an interesting lock that keeps the knob in place when not actively using it. I’ve never used a pen with this feature before, and it is a simple pull to release and use the piston, and a snap back to lock it in place. Ok, maybe more than a simple pull and push - it is a two-handed operation to release - but it’s not going anywhere when locked. For those worried about carrying a piston-filling mechanism and having it twist in transit - like in a backpack, pen case, pocket, or purse - this gives you some extra peace of mind while on the go.

Monteverde MP1 Mercury Orange Fountain Pen Nib

When you arrive, the nib is ready to write, and never stop. This Fine Steel Jowo #6 nib has been perfect from the jump, with no adjustment needed. The feed is not the normal matching Jowo #6 feed, and it flows as good or better than what I would expect from a stock setup. The product description calls the feed “Plasma-treated,” but I have no idea what that means from a technical perspective. All I know is that it works well.

Monteverde MP1 Mercury Orange Fountain Pen Plasma treated feed

With all of that good, I won’t say that there is no bad, but more of a personal nit to pick with the usage of o-rings on this pen. O-rings can be used well, but I don’t believe either of the exterior barrel o-rings add anything to the pen. In fact, they take away. The end of barrel ring, just below the piston, is assumedly there for posting. The problem is that it forces the cap to stop right there, making for an extra long pen when posted. I don’t post, so I don’t use that area, but I’m not sure it is good if you do want to post it.

Monteverde MP1 Mercury Orange Fountain Pen Posted

Longbois.

The MP1 is just shy of 7 inches posted.

The front end o-ring, just above the barrel threads is useful in concept, but doesn’t provide a great user experience. This o-ring is there to seal off the interior of the cap from exterior air entering and drying out the nib when not in use. That’s a good, valid issue with many pens. Monteverde chose this option, and it works well - I’ve had no drying out at all - but capping the pen feels off. It’s almost like the o-ring gets in the way, and the cap is wobbly as you begin to screw it on until you force your way past it. After that, you are sealed and good to go, but capping it was noticeably odd every single time I did it.

To be fair, the TWSBI ECO is designed with o-rings in the same places. Like with the MP1, the end of barrel o-ring isn’t useful unless you want to write with a baton. The front o-ring isn’t noticeable on the ECO until the final turn of the cap, which is exactly where you want it to be. In fact, I had to go grab one of my ECO’s to verify it was even there. The MP1 doesn’t engage in the same way.

Looks awesome, but it may be difficult to see that it is a molded, triangular-ish, grip section.

One not so nitpicky consideration if you like the looks of this pen is that it has a triangular/molded grip section, so if you have a non-standard grip you might want to pass. If the MP1 continues to do well, maybe they mix in a standard grip section, like TWSBI does with the ECO and ECO-T?

The Goldspot exclusive Monteverde MP1 Mercury Orange Fountain Pen runs $63 and includes a 15ml bottle of matching Mercury Orange ink, which is only available with this pen. A wide range of other colors of the MP1 range from $52 to $60, so they are all in the same ballpark. As I mentioned up top, this pen looks and feels great to write with, and the nib/feed combo keeps the ink flowing. The main consideration is if you can work with the molded grip section, or not. I can, so I’m going to keep on writing!

Writech Sprinkles Gel Pen Review

Writech Sprinkles Gel Pen Review

Writech Gel Pens are easily taking over as the new favorites in my planner posse. With their varieties of colors, pen designs, and ink properties, there's something for everyone in their lineup. I've borrowed a few at our planner parties and was impressed (we have planner parties with our friends, right? Where we swap stickers, share pens, drink too much wine and end up labeling three days in a row as Saturday... If not, I highly recommend it). When I saw their products appear in the JetPens arrivals, I decided to try some of my own. I loved the dual-color set I reviewed before, and the Sprinkles appealed to me because I liked this color palette and I'm a sucker for ombre.

Writech Sprinkles Gel Pen

The Sprinkles model has a smooth cylinder body shape in opaque plastic with a lovely color fade design. They have a tinted clear plastic clip and clicker. The clip feels a little weak. I'd hesitate to stress it too much for fear it might break off. But the main body of the pen feels very sturdy. It is sturdy, I can actually say, as I've been hauling them all around work and tossing them in my tote bag with no problem at all.

Writech Sprinkles Gel Pen Knock

The primary feature of the Sprinkles set is that they have a silent clicker. No click! No thunk! It's strangely disconcerting. If pen clicking annoys you or your coworkers, these might be the pens that save you. But I have to say, I miss the click. Sometimes I even forget to retract the tip because my brain doesn't register that I even deployed it at all. It's like the clicks of all the pens over the years have trained me, and without the click, I forget what to do. I think it's cool that this option exists, but I would take an obnoxious thunky clicker over a silent one every time.

Writech Sprinkles Gel Pen Barrel

I have, however, still been using these a lot, because even though they're suspiciously silent, they're great writers. The colors are bright and saturated, the no-smear ink behaves well, the tips are nice and precise, and the colors are perfect for my needs. The refill seems to hold a decent amount of ink, as I've taken a lot of meeting notes with the brown pen specifically, and have no signs of running low. Overall, it's a fantastic set of pens.

Writech Sprinkles Gel Pen Writing

This set of five sells for $12.10 at JetPens, and individual pens are $2.45 each. That's a very fair price for a good set of gel pens. I foresee plenty more Writech pens entering my collection in the future. Just the properly noisy ones, though.

uniball Jetstream Prime 3 Color Lite Touch Ballpoint Multi Pen Review

uniball Jetstream Prime 3 Color Lite Touch Ballpoint Multi Pen Review

I’ve been sleeping on the uniball Jetstream Prime for too long. Time to correct that.

I bought this pen (full name: uniball Jetstream Prime 3 Color Lite Touch Ballpoint Multi Pen) all the way back in February at the California Pen Show. So long ago, I can’t remember exactly who I made the purchase from. All I remember was being surprised to see it there.

The Jetstream Lite Touch had been launched to great fanfare in 2024, and my experience with it has been great. I reviewed the single pen and the 4+1 multi pen at the time, and have mostly stuck with the single version since. My uniball multi pen time has been mostly spent with the 4+1 Karimoku edition (also seen in the linked review, and in this one,) but the Prime has a lot going for it that has me intrigued.

uniball Jetstream Prime 3 Color Lite Touch Ballpoint Multi Pen

For starters, the barrel is slim in diameter for a multi pen. So slim, that on first glance it seems like an upgraded barrel for a single refill pen. And it is a metal barrel, too. Aluminum, but not too light and airy, like some of the 4+1 uniball aluminum barrels. The compact nature means the insides are packed, so it has a solid and balanced feel in the hand. The matte finish on my Burnt Orange model is smooth, but it hasn’t been slippery so far.

The deployment mechanism for the Jetstream Prime is a twist, as opposed to a knock. The look is much cleaner for a multi pen, and for the premium Prime barrel it’s a good fit. The Black 0.5 mm refill is in the center, with a quick twist clockwise to engage Red, or counter-clockwise to engage Blue. You will have to jump over Black in the middle every time if you want to go from Red to Blue, or vice versa. The refill retracts in the zones to each side of the Black refill. The clip does line up with whichever refill you select.

uniball Jetstream comparison

Top to bottom: Single refill Jetstream Lite Touch, Jetstream Prime, Jetstream 4+1 Karimoku edition.

From a writing perspective, you can’t do much better than the uniball Jetstream Lite Touch - at least if you are amenable to using a ballpoint pen. That’s a curse word in many pen circles, but I’m a fan, and will not stand for any ballpoint pen slander! The Jetstream is not your parent’s ballpoint pen, and the Lite Touch is so good, you might not even realize it is one. The best thing I can tell you to do is try it and see for yourself. Maybe not the Prime from the jump, but the single barrel is a good starting point at $3.

The Prime carries an extra digit on its price tag, checking in at $31. Looking at the label on my box, I paid $37 for mine, but that was before the pen became more widely available from importers. $31 seems completely fair for an upgraded barrel like this, although Burnt Orange seems to no longer be available. The four current colors are nice, with the Ivy Green looking especially great.

uniball Jetstream Prime

Only one question remains for me with the Jetstream Prime Lite Touch, and that is how it fits into my rotation going forward. It’s going to take the place of the Karimoku model for now, and given the fact the Prime uses the Lite Touch refills and the Karimoku doesn’t, it might find a permanent home on my desk. At least until the Uni Jetstream Slim Multi Pen 0.38 mm gets the Lite Touch upgrade and they will have to battle it out for supremacy.

Maybe I just swap the refills now.
