Review: Superb - The Muji Aluminium Fountain Pen is a sleek and reliable writing instrument that exceeded my expectations. Its minimalist design is complemented by a lightweight yet durable aluminum body, providing a comfortable and balanced grip. The nib glides smoothly across paper, offering a consistent ink flow without any skips. I appreciate the pen's versatility, allowing me to use various ink colors. The simplicity of the pen, combined with Muji's quality craftsmanship, makes it an excellent choice for both everyday use and professional settings. Overall, a fantastic purchase for those seeking a stylish, high-quality fountain pen without breaking the bank.
Review: Superb pen - brilliant value - I normally use more expensive pens but have recently been trying out different sub-£20 fountain pens to see if any could serve as an everyday, 'chuck it in your bag' pen. The Muji pen really surprised me. It's slim, well-designed, finely machined and looks and feels like a quality pen. It writes beautifully and is very comfortable to hold. It comes with a standard black single-use cartridge, so I've fitted mine with a Faber Castell ink converter which fits well. This pen is really pleasant to use and very good value for money overall. I would recommend it without hesitation.

## Questions & Answers

**Q: Does this take universal cartridges? Some reviews say not and im not paying £1 a cartridge!**
A: Yeah, takes my WH Smiths ones no problem!

**Q: Does the nib write very finely or is between a fine and a medium line?  I want something in between really.**
A: Hi, I use the Muji for drawing. Very reliable and durable and takes a universal plunger/filler reservoir. Hard to say how fine the nib is but I would say it's fine and especially fine if you turn the nib and pen over. I also use Rotring Art pens and gauge nib thickness on these wonderful drawing devices and have the full set from extra fine to broad, again just by turning them over you get thinner lines. 
I hope this is useful. K

**Q: probably a silly question but is this fountain pen authentic and not a dupe of the muji fountain pen? It says muji brand but just double checking  :)**
A: Yes it's a genuine muji aluminum fountain pen

### ⭐⭐⭐⭐⭐ Superb pen - brilliant value
*by J***J on 19 October 2025*

I normally use more expensive pens but have recently been trying out different sub-£20 fountain pens to see if any could serve as an everyday, 'chuck it in your bag' pen.

### ⭐⭐⭐⭐ Great aluminium Fountain Pen, if you like EF tips
*by R***O on 13 November 2023*

I really want to like this fountain pen, but it is not for me. It is made of light but sturdy brushed aluminium, with a very minimalistic look (as you would expect from MUJI). You can use it with international cartridges, or you can get an adapter. Very well-balanced and comfortable to use. My main problem is that I cannot get a smooth flow with the Extra Fine tip. I feel like I need to press more than I am used to, and that creates a slightly scratch feeling in the paper, which I do not enjoy. I am using Waterman Intense Black Ink, but I cannot achieve a smooth and continuous flow, with some letters/words coming up as darker than others, probably due to the pressure issue I am finding. Highly recommended if you enjoy a superb designed all-aluminium Extra Fine fountain pen, but I will save it for signature or special work only.
