FBB series thermoses show the highest results in strength tests, and thanks to the technology of deep vacuum thermal insulation, they keep drinks hot for at least 12 hours or cold during the day. All materials from which the thermos is made are environmentally friendly, safe for health and comply with international quality standards. The thermos case made of stainless spring steel 18/8 AISI 304 is able to withstand external damage and dents. The thermos flask made of food-grade steel with a high content of nickel and chromium is inert in relation to the contents, so drinks are stored in the thermos for a long time fragrant and fresh. A convenient valve-type stopper easily comes off with one click, so you can drink from a thermos or pour a drink into a cup-lid without unscrewing the stopper. The unique coating of the color of the night sky will preserve the original appearance of the thermos for many years. THERMOS THERMOS of the FBB series are incredibly popular all over the world due to their high temperature characteristics, strength and lightness, functionality and practicality, as well as a long service life.
