This Doctor Who pack includes 2 ceramic mini-mugs (or large coffe cups) with a 110ml capacity each. One of those looks exactly like the front of the tardis while the other one has the design of a blue Dalek, one of the most dangerous ennemy of the Doctor !
Considering the success of the Tardis Pop! figure, Funko had no choice but to create a keychain version of the Doctor's spacecraft.
