I know of a way you can just the Joker out of Arkham! You can use the 16 inch tall 81% cotton 19% polyurethane Harley Quinn Checkered Knapsack. That way, you can sneak in a metal file or rubber chicken or deadly chattering teeth or whatever else the Clown Prince of Crime needs to escape! With adjustable straps and belt closures over three pockets, the Harley Quinn Checkered Knapsack is the first step in the road to recovery...if recovery means terrorizing Gotham and their beloved Dark Knight!
