The practical material of the cup makes it perfect for both everyday use and parties or for picnics. At RICE we spend a lot of resources staying on top of the latest rules and regulations regarding food safety and sustainability. Therefore, 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. It lasts for a long time and can go in the dishwasher over and over again... We don't recommend you use food or lidquids above 70 degrees celcious with your melamine. Identify your RICE melamine products by the RICE hologram sticker making sure you get the original RICE quality! You can always find more information about our materials under "Experience Rice" & "Product information". Melamine products are not suitable for the microwave. *Product information may be subject to errors, changes, or sold out items.
