The mug is made of PP. The Mickey and Minnie Mouse design make the mug a real favourite with Mickey Mouse fans. The coffee mug for on the go is a nice companion for the office, university or school. Not only does it look good, but the properties of the leak-proof double-walled insulated mug are not to be underestimated. The Disney to go mug keeps the coffee, tea or cocoa warm for a long time due to the double-walled insulation. In addition, it is leak-proof due to the silicone seal and the cap.
