Coffee cup and flask bodies - although possible we recommend hand washing the cup and bottle bodies to prolong the slip-proof base and avoid heat damage on the colour-coated surface. If you do choose to use a dishwasher keep in mind that any marks on the cup or bottle body that may occur from extra hot washes or the deterioration of the non-slip base are not covered under warranty as hand washing is recommended.
