Hi, not sure if this is the right forum for this but I'll give it a go cause this problem is really bugging me out. I have the really nice Guanleming Calligraphy Pen http://a248.e.akamai.net/origin-cdn.volusion.com/rvbga.avcnm/v/vspfiles/photos/Glm193-2.jpg(photo via ISELLPENS.com) I own two of these bad boys and the suit my needs for a cheep fountain pen for doing quick life drawing sketches. However the pen caps have the nasty habit of coming off in my art bag, pen case, and various other drawing kits. The ink gets all dried out if I don't notice it fast enough and it's becoming a bit of a bother for me. If anyone knows a fix for this or an alternative pen body I could attach my nibs too (that's the real reason why I bought these the really awesome nibs) I'd much appreciate it!
