The KING series thermos mug stands out not only for its original appearance, but also for its excellent functional characteristics. Thanks to the manufacturer's technology of creating deep vacuum, as well as the features of the design and high-quality materials, the SK-1005 thermos mug can keep drinks cool for at least 9 hours or hot for 5 hours. Convenience in use is provided by the exquisite ergonomic shape and unique lid-plug construction with the DrinkLock® mechanism. You can drink from the thermos mug without removing the lid, thanks to the convenient slider that protects against splashing and dust getting inside. The slider rotates 360 degrees in any direction, making it easy to open and close with one hand. "Open/Close" indicators are provided to determine the slider position. The upper edge of the lid-plug is made of stainless steel, significantly increasing its service life. The screw cap is deep enough, equipped with a wide food-grade silicone seal, which enhances the thermos mug's heat-insulating properties and ensures its tightness and reliability in use. There is a special attachment for a tea bag on the inner side of the lid, providing additional convenience for brewing a drink directly in the thermos mug. The lid-plug can be completely disassembled for thorough cleaning. In hot weather, drinks will stay cold and fresh longer if you put ice cubes in the thermos mug - the lid-plug design will prevent them from falling out while drinking. The KING series thermos mugs are manufactured at THERMOS company's own factories under United States Patent D600.071S and comply with the International quality standard EN12546-1:2000. All materials are safe, BPA free, heat-resistant, impact-resistant, and do not release or absorb any odors. The body and inner vessel are made of premium 18/8 AISI 304 Stainless Steel, inert to the contents, allowing not only to maintain temperature but also the taste and aroma of the drinks. The seamless welding and polishing technology make the inner surface of the thermos mug super smooth, so no residue or odors are retained on the walls of the vessel, making it easy to clean. The base diameter allows the thermos mug to fit easily in a car cup holder. The steel color and exquisite shape of the KING series thermos mug give it a stylish and elegant look. It is perfect for both men and women who appreciate quality, functionality, and comfort.
