Hi guys, I just got my staedtler 925 2mm one. It feels nice in the hand and has a wooden pencil like feeling. To be honest I chose it amongst the .3 .5 .7 because it has a metal feed pipe and no fixed lead sleeve. I'm a math guy so I do lots of maths at small areas. I use my gg500 and p205 mostly.(btw gg500 is my first premium mechpen! the first you buy is the best always:D) I bought the staedtler for considerably fair price but felt like I won't use it. I'm not good at sketching or things like that. Should I return it? also I'm leaving my collection feel free to check it.
