If you can't grow one, you can still rock the 'stache with the Mustache Mini Wallet by Whodini Handmade. This is the smaller version of the Mustache Wallet, and at not much bigger than a smartphone, it fits easily in your front pocket.
The Mustache wallet is made of automotive vinyl and clear vinyl, and is screen printed on the inside. The wallet is a mini wallet and has one pocket on each side. The wallet has a velcro closure to keep everything securely inside. Available in brown with a white mustache, black with a mint green mustache, or gold with a black mustache.
