Hi, My Pilot Custom 823 needs new nib. I have few pens wit reg. nib, one italic but I would like to try flex nib and learn calligraphy. I think Pilot FA nib would fit. I am looking for service to order and replace nib and fix one more pen (it is scratchy). Only problem is that I don't like FA nib look, maybe there is other good looking nib good for my setup? Can you recommend service and give me some advice, please ? Arek
