The JNL-500 LB thermos mug with a large silver THERMOS logo on the body is part of a limited collection released in honor of the 120th anniversary of the company that created the world's first thermos. Unique manufacturing technologies, premium materials, and unparalleled user comfort have made the JNL series thermos mugs popular worldwide for many years. The high thermal insulation properties of the thermos mug are achieved through its design features and the innovative technology of creating a vacuum in the space between the body and the flask. This allows drinks to stay hot for at least 12 hours or cold for up to 24 hours. The food-grade corrosion-resistant 18/8 AISI 304 Stainless Steel used in the thermos production is inert and does not affect the taste of beverages. The seamless welding technology makes the walls of the body and flask completely smooth, preventing drink residues from sticking and aromas from being absorbed. The user comfort is ensured by the special design of the lid-plug. The thermos can be used even on the go - it can be easily opened and closed with one hand. To open the thermos mug, simply press the button on the front of the lid-plug: the top lid automatically flips open 180 degrees, locks in the open position, and does not tip over during drinking. The spout of smooth shape with a small pouring hole allows for controlling the liquid flow. The thermos can be placed in a handbag or backpack without the risk of spilling the drink - a special locking ring is provided on the lid-plug. The lid-plug is made of modern copolymers that are BPA-free, mechanically strong, resistant to high temperatures, and do not release or absorb foreign odors. The seal and gasket made of heat-resistant food-grade silicone ensure a tight seal. The lid-plug can be completely disassembled for thorough cleaning of all parts. The innovative technologies developed by the manufacturer and the premium materials make the thermos durable, long-lasting, compact, and super lightweight. Despite its large capacity, the thermos weighs only 210 g. Cycling enthusiasts or car travelers can place the thermos in holders or cup holders - the thermos dimensions allow for it. The practical black coating will maintain the original appearance of the product for a long time. The JNL-500 LB thermos mug with a long service life is a practical and economical alternative to disposable cups. The thermos fully complies with the International quality standard EN-12546-1:2000.
