Secrid 'Slimwallet - Black' Wallet. Unlike the Miniwallet, the Slimwallet does not have the press stud. This makes the Slimwallet even slimmer. Due to its slimness it fits perfectly into the breast pocket of a jacket. Since the Slimwallet's leather cover has a wider cut, the wallet offers space for at least an additional six cards, paper money and business cards in the leather interior.
