## 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
