NEW and improved! We are responding to our customer requirements and have improved the elasticity of the silicone to make it much easier to put on. Of course, the pot remains 100% tight! NON-STICK: The surface prevents food from sticking to the lid - so cakes, fish or omelets can be easily closed Thermomix TM6 Accessories FREE FROM CHEMICALS: The Mixcover Thermomix lids are BPA and plasticizer free, vegan and have been tempered for an extra long time and are therefore absolutely food safe! SUSTAINABLE: Thanks to high-quality silicone, this Thermomix lid can be reused hundreds of times. The lid keeps its shape and always fits perfectly and leak-proof.
