don't bother with this pen, i have one, the LAMY refills needed for this pen are terrible, they don't write. i ordered multiple refills in hoping to get one that works, and after confirming with others online that have the same problem, its just a bad design from them. What makes this worse is that the LAMY M22 is the only refill that fits this pen, so you're left with a light wallet and a useless pen. TBH i don't really think this pen should be offered on massdrop anymore given that it's pretty much non-functional.
