When the dishes arrived with me, I was very positive about the workmanship and quality surprised. As I could read already in a previous review, the product will be seen on the bottom of the bowl, actually produced in Korea Komax for Emsa. The bowls are temperature resistant from -40 to +110 degrees Celsius. EMSA is on the product 30 year warranty. To add to the many reviews about the microwaveability something I type here simply times the original instructions from. Before first use: Please rinse the cans once by hand or in the dishwasher. Stickers and product insert must be removed. Instructions for use: 1. Use the cans in the microwave just for defrosting and heating, not for cooking the food. 2. simply open When used in the microwave all closure clips on the sides, so that the pressure can escape and the lid to use as a splash guard. 3. When used in the microwave also can heat the can itself - expect some take out. 4. Especially fat and sugary foods and dry take much more microwave energy to an aqueous foods and can reach very high temperatures. You may want to heat these foods carefully because the maximum temperature of +110 degrees Celsius can be quickly exceeded. (. Eg tomatoes, paprika, curry, carrot etc.) 5. Strong carotene-containing foods and spices can discolor the plastic - but without any reduction of functionality and quality. Cleaning and care Clip & Close is dishwasher safe. Avoid at Hand Rinse please aggressive cleaning agents or scouring pads, as well as the use of pointed, sharp objects, as this affects the durability of the plastic. I would always buy these bowls again, for me a very good product at a reasonable price therefore 5 Stars.
