Keep the skinny tumbler trend going with this heat-sensitive tumbler. The original color of the tumbler is orange and will change to a yellow color resulting from external heat (being held). The color of the tumbler will not change if a hot beverage is poured into the tumbler. This 20oz skinny tumbler is sublimation ready and measures 8" tall. It can be printed using a mug press or convection oven. Straw included.
