Clay Cups are handmade stoneware and need to be treated with care. While they are dishwasher safe, we do recommend hand washing your Clay Cup in warm soapy water.
Our corks are treated with a liquid quartz sealer, making them food safe in line with Germany's food safety standards. This sealer helps to repel liquid and prevent mould, however since cork is a natural product discolouration over time is normal and safe. Corks are not dishwasher safe and must be hand washed gently in warm soapy water only.
