The design also changes as the drink cools, making temperature changes visible. The black mug has a large handle for a comfortable grip and can be used for coffee, tea or cocoa. A fitted polystyrene insert inside the box helps protect it during transport.
Care: clean with a damp cloth and avoid harsh cleaning agents. Avoid knocks and drops. Store in a dry place away from direct sunlight and heat sources.
