Your wallet goes through hell, mine personally has been covered in icing, attacked by a cat and gone for a wash. What this means is that you need a wallet that is long lasting and resistant to abuse or claws. That is why I find it so easy to recommend the Kanken Card Wallet from Fjallraven . It has been made with their signature G-1000 material which is long lasting and water proof. Along with the sleek design and utilitarian aspects make this one for your pocket!
