What materials is the IRISgo® cup made of?Updated 7 months ago

The IRISgo® cup is made of three different materials. The lower part is made of double-walled vacuum-insulated stainless steel, which keeps your drinks hot or cold. The upper component is made of polypropylene, which is BPA-free, easy to handle and offers a pleasant drinking experience. The cap's membrane is made of 100% highly elastic and temperature-resistant silicone. It is also odourless and food-safe (FDA-compliant).
