NOT FOR PUBLIC USE
The TARDIS may say “For use of public advice & assistance,” but we know it’s mainly the good Doctor and companion who have access to the contents within. Shouldn’t the same be true for the contents of your backpack?
This Doctor Who TARDIS Backpack (like its namesake) provides a surprising amount of storage within. The tradeoff though is that you probably can’t fit in it yourself… it might break. But if you manage it, let us know if it leads you to a real TARDIS.
