Review: Oh how I love this fountain pen - excellent for drawing - I first tried one of these fountain pens a few years ago. I love how, even though being a fine point, the ink just flows without skipping. It is an excellent pen for inking drawings, and it's never given me any troubles. Until I lost, misplaced, or had it stolen. When I couldn't find my pen, I decided to buy another one, which I did and I was VERY happy that it's quality, look and feel and writing experience remain the same. I like how thin this pen is and how the cap slips onto the back of the pen while in use. It's a flat aluminum colored pen and it comes with cartridges filled with black ink. They look to be international standard type so I imagine you could get any color ink refills you'd like, I usually just use black in mine. This is a good beginner's fountain pen because of how easy it is to use, it just works without issue -- there is no "breaking in" or adjusting the nib, of the several I have purchased and used over the years, none have given me issues or need to be adjusted. Writing is comfortable and not a strain, much like writing with a regular pen or pencil. I likely will buy it again.
Review: Great ink flow - Pen is an affordable and great starter fountain pen. Ink flow is great and NIB doesn’t bleed. You will need to order additional cartridges as it comes with 1. The pen is extremely light, but becomes too heavy with the top attached. Overall, great pen at great value so far.

## Questions & Answers

**Q: What converter would be compatable with this pen?**
A: in this pen, it requires a standard international converter, but since the shape of the intake is slanted like a standard international cartridge, many of the chinese standard int'l converters won't work (since they're like cylinders with standard int'l bore, and not tapered). you're gonna wanna look for a standard international converter that has the smaller, slanted part at the front instead of just being a barrel.

brands that do fit: schmidt (the K5), monteverde, montblanc, waterman, rotring, and some select moonman ones.

brands that do NOT work (unless you're willing to file off some from the front to make it fit): jinhao, hero, penbbs, most chinese brands.  

basically any standard international converter that costs more than $5 will probably fit lol. 
i'd recommend the schmidt k5 because this pen has a schmidt nib/assembly, so it's like for sure compatible.

if anyone finds a cheap chinese brand that has a properly shaped converter, please contact me because so many pens have this problem, and i want to buy 20 of them.

**Q: What size nib us on this pen?**
A: By comparing this with other pens I have, I would say this is a bit finer than 0.7mm (medium), but visually heavier than 0.5 (fine). Frankly, if it were near a fine nib, I wouldn't like it; and I like this pen a lot!

**Q: What size is the nib?**
A: It's a fine nib. Good flow. Smooth writing.

**Q: Does it come with ink?**
A: Yes, one ink cartridge is attached.

### ⭐⭐⭐⭐⭐ Great ink flow
*by B***Y on August 4, 2026*

Pen is an affordable and great starter fountain pen. Ink flow is great and NIB doesn’t bleed. You will need to order additional cartridges as it comes with 1. The pen is extremely light, but becomes too heavy with the top attached. Overall, great pen at great value so far.

### ⭐⭐⭐⭐⭐ One of my best pens
*by J***J on August 21, 2024*

I have a collection of 20+ fountain pens ranging from $11 to $350 each. This is in the top three quality-wise, and bottom three price-wise (so inexpensive for what it is!). It’s very smooth, it behaves very well on many types of paper, the grip is fantastic (not slippery or stepped like a Pilot Metro), writes very consistently with stock ink (although my favorite ink is Platinum Carbon Black, which you can refill the cartridge with using a syringe), does not leak and is easy to clean if it does, is very giftable, etc. I have had 10+ friends and family members test out all my pens on FP-friendly paper, and this pen almost always falls into their top three as well. I recommend getting a refillable piston-style cartridge for it and a bottle of your favorite ink to prevent wasting the plastic cartridges (and the money needed to keep buying them). Hot tip: Muji’s notebooks are also FP friendly, specifically the tan 184-page “POCKETNOTE” book with the red ribbon (pictured). There is no bleed and very little ghosting even with black ink. Do yourself a favor and get this pen if you are just getting into fountain pens — you will not regret it, and will likely keep coming back to it even as your collection grows :)
