The FBB series thermos is the hallmark of the world-renowned company Thermos, specializing in the production of insulated products since 1904. FBB thermoses show the highest results in strength tests and confidently maintain leading indicators in temperature retention: thanks to the technology of deep vacuum insulation of the interstitial space, the 0.750 liter FBB thermos keeps drinks hot for at least 18 hours or cold for up to a day. All materials used in the thermos are environmentally friendly, safe for health, and comply with international quality standards (BS EN12546-1:2000). The body of the thermos is made of 18/8 AISI 304 Stainless Steel, capable of resisting external damage and dents, and will maintain the original appearance of the thermos for many years. The thermos flask is made of food-grade steel with increased nickel and chromium content, inert to the contents, so drinks stay aromatic and fresh in the thermos for a long time. The convenient valve-type cap opens easily with one touch, allowing you to drink from the thermos or pour the drink into a cup without unscrewing the cap. The thermos is sealed with food-grade silicone gaskets - an inert, durable, and heat-resistant material. The steel color accentuates the strict design of the model. Thanks to its compact size, the thermos easily fits in a business briefcase and takes up little space in a backpack. The diameter of the thermos is suitable for most bicycle holders and car cup holders. Thermos FBB series thermoses are incredibly popular worldwide due to their high temperature characteristics, durability, lightness, functionality, practicality, and long service life.
