The detachable closure is dishwasher safe and hygienically clean. A safety lock prevents unintentional opening. The bottle is equipped with Thermos insulation technology, which means double-walled stainless steel with vacuum insulation. Impact and break resistant. Without inner coating, therefore tasteless.
