Although the ink is durable, I always recommend hand-washing your tumbler to extend the life of your Sunny Belle product. Do not soak or place in the dishwasher. See below for more info.
What’s sublimation, you ask? It’s basically a process where special ink is permanently transferred to your tumbler (not vinyl). The permanent ink is gorgeous and durable and the customization possibilities are limitless!
