czxwyst C1 Eyedropper Filling Fountain Pen Double Ink Filling System Original Box (Transparent, Fine Nib 0.6mm)

I love everything about this pen. It looks cool, it writes well. The nib is smooth, but has just the right amount of resistance for my preference. The acrylic grip is smooth and comfortable to hold. I find my writing looks nicer than with my other (similar but slightly more expensive) fountain pens. I only wish the C2 could be purchased with more color options for the grip. This one is pretty, but I’d like to buy more pens so I can have them inked up with multiple colors.The pen hold a lot of ink and keeps it fresh. It closes securely and the ink stays fresh for months even until you use the last few drops. I have other fountain pens where after a much shorter period of time, the ink seems to start evaporating and coming out very concentrated and dark.

I took the included pump-converter cartridge and put it to use in another pen. It's nice to have as an option! Then I filled the Moonman pen putting ink into the huge reservoir with the included eye-dropper. The pen writes extremely well, very smooth, ink flow start up very good, nicely balanced in the hand. As good or better than certain German fountain pens costing ten times as much! (which I also have and use) This is the second Moonman I have purchased on Amazon, I like them so much.

If you’re looking for an affordable eyedropper fountain pen, it’s hard to do better than Moonman in general, and specifically the new C1. First off, it’s a beautiful, classy looking instrument, and the build quality is surprisingly solid for this price point. Interestingly, it does come with a converter, so if you’re not comfortable eyedroppering the pen, you don’t have to. But jeez, it sure is pretty filled with Noodler’s Polar Blue sloshing around. Also included is a pipette for filling the reservoir with ink, but I used my ink syringe.Out of the box, my nib was scratchy. But a few passes with micro mesh cleaned that right up, and now it’s one of my smoothest writers. It is advertised as a fine, but seems to write more like a medium. The nib is a number six, rather than the smaller number five 8n the M2, which pleasantly surprised me. The grip is not only aesthetically pleasing with its swirls of red and purple, but it also fits quite well in hand.You CANNOT post this pen as the cap will not fit on the back of the barrel. But I find it quite comfortable and well-balanced unposted. I am a lefty overwriter, so your mileage may vary. I’d say the pen is roughly 5 inches unposted.Overall I am very pleased with my C1, and it’s in my everyday rotation. Is an Opus 88 a better eyedropper pen? Well, yes, but it’s also four times more expensive. You’d be hard pressed to do better than the C1 for the money. Pull the trigger.

I love fountain pens and have owned many over the years. My biggest gripe with many past fountain pens have been the problems with the pens mechanically malfunctioning, usually some issue with the nib, clogging or jamming, perhaps from ink drying or some other mechanical issue requiring repair or replacement. This pen just keeps on going, the enormous reservoir is likely one of the ways this pen just keeps writing. The ink just continues to flow almost indefinitely. I can write for a couple weeks before refilling. I have for one of the first times gone through most of a bottle of ink with one pen. I will definitely buy another one of these and maybe a few additional ones when mine finally stops writing. In addition to being functional, this pen is very beautiful, with the bright blue ink I filled it with nearly glowing through the clear acrylic. It has a small flattened side that allows the otherwise mostly round barrel to not roll on table but to simply lie motionless so you can admire the pure color of ink in the reservoir.

Beautiful and crystal clear. I have the medium nib, which I like. I have very small hands and the grip is a tad large for me but it's still one of my favorites because of smooth writing, large ink capacity, and beauty.

Loved the look of this pen! Watched a bunch of reviews and decided this would be a good buy. Unfortunately, it just didn't work out well for me. While it initially worked OK (note: ink did not immediately flow like some of the higher end pens I have, but that's ok), by day 3 this was no longer the case. Currently it only writes on the reverse nib position and i cannot get the ink to flow in a regular position. When it did work, it was very smooth and an enjoyable experience.The other thing i will note for those with smaller hands -- i found this pen to be slightly uncomfortable to hold. I like to hold my pens a little higher up but could not do that with this pen b/c it's quite wide once you go past the step up. If you don't mind bigger pens or hold closer to the nib anyway, this will not impact you.

This fountain pen is a great writer out of the box! I love that this is an eye dropper. The pen holds a lot of ink. If you’re worried that the nib will be too fine, don’t. It writes like a medium nib. If you’re concerned that the pen will roll off the table, it won’t. There is a subtle flattened side of the pen that prevents that from happening. I’m considering getting another one to see if I can get a pen with a red colored section. The one I got is more on the purple side. The pen comes in a nice gift box as well.

The media could not be loaded.  Fast delivery. Really nice pen for the price. Could be a perfect beginner pen. Fine is a very "medium" nib (I expected this, others may not). Just a delight for the eyes in simple lines and great function.

this is likely the best steel nib for this price point. no nib tweaking needed - wrote smoothly out of the box, even for a fine nib. the acrylic barrel is crystal clear - using it as an eyedropper no issues at all

Great pen, current daily driver
