This is were I get mine he is very helpful just send him a message and he will cut you some normally 25mm
I dont know if you are aware of the laws about wedding pens a lot of registrars wont allow you to use your own pen and you have to use permanent ink by law I would hate you to sell a pen then they find out they cant use it you could end up with a law suit against you
You have to tell them to check with the registrar or the vicar first to see if he will allow them to use it some are very helpful but some can be right pigs and it is up to them at the end of the day
I'm fully aware of the laws on the matter ,Woody...but thanks for the heads up ..
