Hi guys, I recently bought a Mulberry men's wallet, style here: http://www.mulberry.com/#/storefront/c5492/4740/moreviews/ Its previous owner haven't used it but it's pretty old. For example, instead of the current stamped logo as seen on the website, it's gold and says Mulberry (tree logo) Company, with Made In England below. Anyhoo, my issues are: 1) The slots are rather tight for cards now. Is it OK if I wrestle 1/2 cards into them to stretch them out? I've been doing so for a month or so and it seems to be working, but I don't want to strain the seams or overwork the leather. 2) The cards get stuck to the slots and it's difficult to take them out, even when I've stretched the leather. Is there a treatment to make the leather less 'sticky'? Thanks for any ideas provided !
