Made of food-grade silicone, they are dishwasher safe, but they can also be easily hand washed. Wide base provides stability and heavyweight thickness life. Use them with hot and cold beverages. Cold drinks will stay cool because the thick walls keep liquids cool. Coffee, tea, and other hot beverages are great too! Ideal for outdoor and indoor areas. Our silicone is non-toxic and safe for food and drink contact. Our silicone will not react with food or drink, nor will it produce any harmful fumes.
