The Doctor's time machine is (say it with me...) bigger on the inside, which means there is plenty of room inside for all the delicious treats you could possibly want. If you aren't a Time Lord or Lady, however, you can keep your cookies inside this TARDIS cookie jar with sound effects.
Would you like to guess what the sound is? I'll give you three guesses and the first two don't count. Yes, it's the iconic whirring and wheezing sound that she makes every time she travels, a sound River Song told the Doctor is caused by the fact that he leaves the parking brake on.
The plastic container has a hinged lid that flips open when you want to put something inside or take something out. Opening the lid activates the sound, as does pressing on the light on top. Speaking of the light, it lights up as the cookie jar tries to dematerialize, but fortunately for you and your dessert, it seems to be stuck and will stay in your kitchen where it belongs.
The inside has a removable liner that you can take out to clean whenever you need to. The inside dimensions for the liner are approximately 4" wide by 8" tall, which makes it the right size for small cookies such as Oreos or Jammie Dodgers. You can also keep Jelly Babies inside, but no matter what kind of treat you keep in the TARDIS cookie jar, chances are they won't last long!
