It holds 350ml and suits tabletop players and video gamers alike, whether they run dungeons on a Friday night or chase high scores till 2am. Hand wash only, and skip the microwave, as heat change coatings need gentle treatment to keep performing the trick.

Can it go in the dishwasher?
No. Hand wash it gently so the heat reactive finish lasts.
