Sailor Que Será Erasable Gel Ink Pen Review

Sailor Que Será Erasable Gel Ink Pen

They are trying.

And you know what? I give Sailor credit for that. As Pilot has proven with the FriXion, there is an enormous market for erasable gel ink pens. Pilot has been perfecting theirs for 20 years, which is important context to keep in mind as I go through the rest of this review, because the Sailor Que Será is not a good pen. Yet.

The Que Será was launched by Sailor earlier this year, with an ink formulation designed to differentiate itself from the FriXion. Where the FriXion uses thermo-sensitive ink and erases via heat generated by friction, the Que Será designed their ink to essentially sit on top of the page, and allow the eraser to “peel” off the ink, similar to a traditional pencil erasing experience.

Shades of a Sharpie marker, but with Pentel parts on the front end.

That may sound weird, but it works. The eraser marks are mostly clean, although there is some mess left behind, again, like a standard pencil. This time, it’s ink bits, not eraser bits, left on the page that need to be brushed off. This ink formulation does mean your words are actually erased, unlike with the FriXion, where the words can be “restored,” by placing the page in a cool area, like a freezer.

While it’s main feature, gel ink that erases, works well, the general writing experience is one of the worst I’ve had with any standard pen, erasable or not. That’s a problem for the Que Será, because I’ll never get to the main benefit if I don’t enjoy writing with the pen in the first place.

Sailor Que Será Writing

I was sent two Que Será pens by a friend - one Black, one Red - each with an 0.8 mm tip size. From my first lines the writing experience was underwhelming, and with more use it escalated to downright bad. I think the good part of the ink formulation - the erasability - plays directly into the poor writing performance. The ink sometimes builds up on the tip, making my lines messy, but more annoying was the constant railroading of the lines on the page.

Sailor Que Será Brushed

Brushed off. You can still see the underlying writing like with almost any erasable product, and I could take another pass to erase more fully.

Railroading is an effect where you see white space in the lines on the page, usually in the middle of a mark. It was constant with both Que Será pens, but more noticeable with the Black. I did try to wipe off the tips on occasion, but that was a fool’s errand. They started bad, and stayed that way. On top of that, their pigmentation was light compared to standard gel ink options.

Sailor Que Será Close-up

A close-up of the writing. Look at the vertical lines - especially every “T” in both colors - not good.

While all of this is bad for the current iteration of the Que Será, I wonder if they can find their footing like Pilot did with the FriXion? When it launched, the ink was very light - the Black much lighter than the current Que Será - and the erasability was only average. It didn’t work well enough to be an every day pen, but Pilot stuck with it, and turned it into a high-quality gel ink pen that, almost as a bonus, has great erasability if that’s a feature you need.

What path will Sailor take with the Que Será? We can only wait and see. Now that Pentel is also under the same corporate umbrella as Sailor, can they continue to iterate and improve on it together? I hope so, because competition is good, and right now, the FriXion continues to have none.

Uni-ball R:E Erasable Gel 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 Twitter.)

The Uni-ball R:E Erasable Gel Pen seems to be aiming to create some competition for the Pilot FriXion with this new line of erasable gel pens. There are a lot of similarities between the two. Uni improves the body design in some ways, I think, but hasn't improved on the overall ink quality. The FriXion pens have been fairly popular, and fans of Uni-ball may like these as well--but I have a lot of issues with them.

The feel of the pens is great. It's a sturdy, good build and doesn't feel like it's too delicate or flimsy. It has a nice rubber grip, decent clip, and a satisfying click mechanism. The eraser is located under a clear plastic cap on the click button. Uni has devised a special system that prevents the pen from clicking when it's inverted, so you can erase without retracting the tip. I noticed it sometimes takes an extra shake to disengage the lock mechanism. It also means that if you're in the habit (like me) of flipping your pen to click it against your leg or the desk, you'll have to adjust. The clear plastic cap that covers the eraser also has a short life expectancy. Being tiny and clear, if it rolls away, it may be difficult to find.

The ink is where my real issues with the pen come in. It's very unsaturated, as all of the erasable gel inks I've tried are. The black is really grey, and all the colors have a muted look to them. Uni accounts for this by calling the color "Off-Black", but I think that's marketing speak for "as close to black as we can get it". The muted tones are pretty, if you're expecting muted tones. I don't dislike the colors--I even love the orange in this set--but I'd love to see some more vibrant tones in the line.

Like the FriXion pens, the ink is heat-reactive. It's the heat from the friction of the plastic eraser that causes it to disappear. The eraser never wears down and doesn't leave a messy residue or dust. It does an okay job at erasing. It doesn't leave totally clean paper, but it's close. However, after about ten seconds, some of the ink begins to reappear. The pink and red did this the most--after about ten minutes a large portion of the erased area had reappeared, even at room temperature.

Because the ink disappears at temperatures over 140 degrees, and reappears at temperatures under 14 degrees, it's not recommended for important documents, signatures, or addressing envelopes. With ink that might disappear at any time, I can't think what it might be good for except for magic tricks and espionage. Every time I try to write with an erasable gel pen, I end up putting it back because of this volatile trait. I can't help but think of it as unreliable ink.

Toasted!

It's totally fun, though. As an experiment, I wrote a test page, and then I held it over a warm toaster. The ink vanished in seconds--though when I held the paper at an angle to the light, I could still see the texture of it on the page. Then I stuck it in the freezer. All the ink returned in less than three minutes, though even more muted than it had been before. It's a cool trick, but I wouldn't want it happening to my class notes or journal pages. While you can always freeze your page if your ink disappears in a hot car, if you've erased your work and then written over the same area--and then your page gets cold--you may have trouble reading the text. It can't be un-reappeared.

Frozen!

If you love erasable gel pens, and you love the Pilot FriXion, you might want to give these a try. They're a great version of a product that a lot of people enjoy. But the unreliability of the ink is a deal-breaker for me. It might be because I live somewhere that spends a good portion of the year below 14 degrees, but it all sounds too risky. I'd only use them to write something fleeting and unimportant, but I don't need 8 colors for that. Would be swell if I had black, though.

Pilot FriXion Ball Slim 0.38 mm Orange Review

Pilot FriXion Ball Slim

If you didn't know this already I am a big fan of orange. Orange pens, orange barrels, orange inks, orange detailing, pretty much anything orange. There is no real reason why, other than the fact I am not a fan of red, so I use orange as my red replacement.

What I have never been a huge fan of is the Pilot FriXion line. They are completely fine pens, but usually not for me. They are growing on me though, especially as the product line matures. I think the turning point for me was the FriXion Biz, which is the only FriXion I use regularly, but the recently released Pilot FriXion Ball Slim may join the club.

The Slim has two things going for it: An ultra-fine 0.38 mm tip, and a slim but comfortable barrel design. I like these slim single cartridge barrels more than I ever thought I would, starting with the Uni-ball Style Fit. The FriXion Slim feels great in the hand and is very manuverable. The knock is placed subtly on the side of the barrel allowing for the eraser to be placed properly on the top of the pen.

I think the 0.38 mm tip is even finer than that. It writes more like a Uni-ball Signo DX 0.28 mm to me. That means there is some scratchiness when writing, which should be expected on a pen this fine.

Where the FriXion runs circles around other pens in this category is erasibility. No other company can hold a candle to Pilot in this area, so if an erasable gel ink pen is what you need, look no further than the FriXion.
