I have an Estie J that has the wrong size cylinder in the base of the cap (the inner cap ); the hole is too small to accomodate any renew nibs. The pen came with a smaller knock-off nib that fits but writes poorly. How do I remove this part and where do I find a replacement? I'd like to outfit the pen with a better nib.
I've already posted this in the Estie forum but have yet to receive a reply.
