Made from 50% polyester 50% polyurethane and perhaps a slight dash of Ooze, the 18 inch tall  adjustable strap TMNT Turtle Shell Backpack with Masks & Weapons is like being one of the famous Heroes in a Half Shell...but with the ability to actually load said Half-Shell up with stuff! Oh, I bet the Teenage Mutant Ninja Turtles would kill to be able to load their shells up with pizza and skateboards. I don't think you'll be able to get skateboards and pizza in the TMNT Turtle Shell Backpack with Masks & Weapons, but it should hold all of your other stuff with relative ease. The storage area of this fantastic backpack has several sleeves for writing instruments and places for knick-knacks like throwing stars or smoke pellets. Coming with two sets of plastic weapons (numchucks and sais) and a red AND orange mask, the TMNT Turtle Shell Backpack with Masks & Weapons will allow you to emulate either Michelangelo or Raphael!
