This R2-D2 Knapsack Backpack is the bag you have been looking for. It will allow you to carry a droid on your back, which in turn, will hold all of your important stuff – like books and Star Wars toys for instance. You should never leave home without some Star Wars toys.
This backpack will make you too cool for school and has enough pockets to hold all of those gadgets that R2 uses to get out of tough situations. You may even find a holographic message from a Princess inside.
Just watch out for Jawas. They will try to steal your backpack and sell it on the black market.
