Make your own Moo card case from a starbucks gum case and sandpaper
Step 1: Get Gum From Starbucks
Go to your local starbucks, pick up a tin of chewing gum.
Step 2: Sandpaper
Find some fine sandpaper and start removing the printing on the tin.
Step 3: Bend the Inside Metal Fold
Take some pliers and bend the fold of the metal on the inside of the tin, so the moo cards don't get stuck.
