Ingenious temperature effect: When hot liquid is poured into the elaborately printed mug from Dino World, a previously invisible, cool background from the dinosaur era appears around the large Tyrannosaurus rex. After cooling down, the background disappears again. The mug holds 320 ml of your favourite drink and comes packed in a high-quality gift box. Due to the print, the mug is not suitable for use in the microwave or dishwasher. Material: New Bone China porcelain
