It's not a problem Phil, I have done it on other kits on here as I have no alegiance with any specific suppliers.
I understand that very reason for cap thread, but my customers use their pens daily so it will put them off very quickly. Handed it over as a freebie to one today and she picked up on that straight away. Liked the feel of the pen though.
I agree that Chrome would nock it back so stick to higher end platings.
What members would need to understand that where the Mistral kit is positioned in pen kit world, there are so many cheap Gent kits and the like that once dressed up in the same blank would look as good in a picture.
That's what can put them off buying a higher priced kit such as you are selling, that said the entry level kits sub £10 have a place in the market much the same as yours does,
