The cup is made of melamine - a practical, durable and essential material for weekdays, celebrations, picnics and more. At RICE, we focus on food safety and sustainability, and our melamine is of the highest quality, recyclable and free from bisphenol A and phthalates - we love the material and its endless possibilities... You can always find more information about our melamine and other materials at "Experience RICE" and "Product Information". Our plates are also available in this lovely fiery fuchsia colour - so if you are (like we are) absolutely crazy about our plain items, then have a look at our other lovely colours. Mix and match the colours as you want or add your favourite RICE print. Fun, funky and colourful functionality! Melamine is super convenient... High quality, durable, longevity - and you can put it in the dishwasher! Recognize your rice melamine product on the RICE hologram to ensure you get the original RICE quality. Melamine products are not suitable for microwave.
