Halloween-themed mug that changes color at 60°C or higher. - Brand: Mercedes-Benz - Design: Halloween motif - Temperature Change: Changes color at 60°C or higher - Material: Ceramic - Size: Approximately 300ml Not for sale, limited to users. The cup changes color depending on the temperature! One cup does not have a plastic bag in the box. I'm not sure if that one has been used, but it's in like-new condition. Thank you for looking.
