Found these in the Leigh store, but been spotted in other stores to. Really good price since you can pay about £2 for a standard Mr Men/Little Miss mug/cup. Nit suitable for dishwashers and microwaves though.
They had Mr Bump, Little Miss Chatterbox and Mr Greedy in that store. Other designs are available though like Mr Grumpy and Mr Strong, so other stores may have those. Added a pic in first post of all the designs
