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.
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!
