The 4.5'' by 3'' by 8.5'' Doctor Who Tardis Tin Tote is an awesome way to contain your pencils, chronological devices, and sonic screwdrivers but you won't be able to ride this great tote around. It doesn't have the normal TARDIS effect of being much bigger on the outside! That sort of technology is crazy expensive and there are certain rules against unauthorized access to the time stream. We are just looking out for you, you know? You are still clear to get the Doctor Who Tardis Tin Tote though!
