Regarding the material: made from 100% sugar cane and minerals and nothing else! The sugar cane juice is the main ingredient of the raw material with minerals used as a filler. The so-called mineral filling means that the material is reinforced with mineral fillers in order to achieve a corresponding "performance" of the material, such as stability, heat distortion resistance or scratch resistance. Together, these raw materials produce a high-quality biopolymer, from which the products are manufactured using the injection moulding process. Without melamine and without plasticizers such as BPA & Co. Other specs: Stackable Fully recyclable dishwasher proof Co2-neutral Odourless and tasteless
