The around 19" high x 13" wide x 9" thick Star Wars Force Awakes BB-8 Backpack Buddy is made from polyester fibers and will allow you to carry a few knicknacks! I know what kind of stuff R2-D2 carries, like hidden Jedi messages and lightsabers, but what does BB-8 carry? Stuff like the old Star Wars movies and lensflares, on account of his work with JJ Abrams? I guess you won't know unless you get the adjustable Star Wars Force Awakes BB-8 Backpack Buddy!
