Never travel through time and space without your Doctor Who Tardis Heat Reactive Travel Mug. This 20oz Doctor Who Tardis Heat Reactive Travel Mug is like magic, much like the TARDIS herself.
This mug is not bigger on the inside, but it will hold your coffee and keep it fresh. It makes a fun gift for Doctor Who fans on the go, but I would get one for myself too. When you put hot liquid in it the TARDIS appears.
Only $19.99 from Superherostuff.com.
