These cute small cups are made of melamine - a practical, strong, and durable material... The miniature cups are an essential part of your tableware selection. At RICE we spend a lot of resources staying on top of the latest rules and regulations regarding food safety and sustainability. RICE melamine products intended for food and beverages are tested food safe and are approved by DVFA. We make sure our melamine is of the highest quality, reusable and free of bisphenol A and phthalates - we love this material and the many possibilities it holds... pretty, practical, long-lasting, and can even go in the dishwasher. Melamine products in general are not suitable for the microwave. Identify your RICE melamine products by the RICE hologram sticker to make sure you get the original RICE quality!
