The classic KING series thermos is famous for its reliability, magnificent appearance, and impeccable characteristics. Drinks stay hot or cold in it for over a day thanks to the unique THERMOS vacuum insulation technology, premium materials, and structural features. The SK-2010 thermos models are manufactured at THERMOS company's own factories under United States Patent D572.981 with compliance to the International quality standard EN12546-1:2000. The 18/8 AISI 304 food-grade stainless steel flask is inert to the contents, does not affect the taste and aroma of the drinks. The steel body provides strength and resistance to mechanical damage. The screw cap is made of heat-resistant food-grade plastic that is BPA free, does not absorb or release any foreign odors. The thermos seal is provided by a food-grade silicone gasket, a hygienic hypoallergenic material resistant to high temperatures. The thermos' insulation properties are enhanced by the deep cap, which has special grooves for pouring drinks, allowing the cap to be partially unscrewed. To pour the drink into the lid-cup, simply turn the cap half a turn. Liquid flow indicators are provided on the top side of the cap. The SK-2010 thermos with a practical matte khaki coating is a worthy addition to the KING series lineup.
