Review: Beautiful - What a Fantastic Fountain pen Smooth and Elegant Works with art and writing Such an investment
Review: I own many fountain pens (possibly too many) and this is one of my favourites. It's compact, comfortable, very light, and stylish. It also has one of the smoothest nibs I own which makes it a pleasure to write and sketch with. In fact it has a smoother nib than other pens in my collection that cost ten times as much making it fantastic value. I've no idea if I was lucky to get such a smooth nib with my first Muji fountain pen but I've read other positive accounts so perhaps it's a sign of great quality control. The only minor negative point I can think of is that it comes with only a small international cartridge but this means it can be used with a large international cartridge or convertor so it's easily remedied. Some people classify this as a starter pen and while I think it's true that its low cost and ease of use put it in the same league as the Lamy Safari and Pilot Metropolitan and it's not as fancy as high-priced pens it's definitely a pleasure to use at any time. Highly recommended.

## 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.

### ⭐⭐⭐⭐⭐ Review
*by M***L on 5 November 2020*

Es una pluma muy elegante y muy bien hecha, de una calidad muy buena para el precio que tiene, el cuerpo y la pluma en sí no se le puede poner ninguna pega, el acabado es mecanizado y perfecto y el plumín es de acero inoxidable con punta de iridio lo cual no es común en plumas de este precio y da una sensación de escritura muy suave y muy agradable. El punto negativo a ese respecto, es que no es una pluma de uso intensivo por su forma y ergonomía, y cuando llevas escribiendo un rato a ritmo intenso, con mi forma de agarrarla al menos, se me hace bastante incómodo y hasta me llega a hacer daño. Para uso no intensivo o esporádico o para colección es una pluma muy interesante. La uso con un convertidor pelican y he probado varias marcas de tinta y funciona perfectamente con todas.
