  • Care

    We recommend hand washing your mug. This mug is printed with a water-based paint followed by a clear protective coating, or a powder coating, which can deteriorate when regularly exposed to high water temperatures and the rigorous environment of a dishwasher. For best results, wash your MiiR product with a long-handled soft bristle brush, biodegradable soap, and warm water.
