I have to admit having seen the Epsilon in my hand today it isn't a bad looking kit, i had in my mind that the balance wasn't right with having a long nib, well i was wrong ..
All three pens look good Dan .. :wink:
Sorry. Just noticed that you asked about sigma and not epsilon. Both tubes on the sigma are slightly bigger than the OMEGANice Dan, I haven't had chance to make the Sigma you sent me, what size are the tubes?
