The special style and concise design of the NS-402 thermos cup make it modern and ultra-fashionable. The refined and elegant shape complements the impeccable properties of the thermos cup, keeping drinks hot throughout the active day or cold for up to 24 hours. The high thermal insulation characteristics of the thermos are provided by the innovative vacuum insulation technology developed by the manufacturer and used in the production of the thermos. The body and inner flask are made of food-grade corrosion-resistant 18/8 AISI 304 Stainless Steel that does not interact with the contents and does not affect the taste of the drinks. The special treatment of the steel using seamless welding technology makes the walls of the thermos cup completely smooth, so drink residues do not stick to them and their aromas are not absorbed. The convenience of use is ensured by the features of the thermos cup design. It can be opened and closed with one hand - left or right. By pressing the button located on the front part of the lid, the top part automatically flips open and locks in the open position. The spout of smooth shape with a small pouring hole allows you to control the flow of liquid. The locking ring prevents accidental opening of the thermos when placed in a bag or backpack. The lid is made of modern Eastman Tritan® copolyester, combining the best properties of glass and food-grade plastic. Tritan is characterized by thermal resistance, special strength, does not contain bisphenol A (BPA free), does not change color, does not absorb or emit foreign odors, and provides a pleasant tactile sensation. The food-grade silicone gasket and seal provide the thermos cup with airtightness. All materials used in the thermos cup are safe and environmentally friendly, suitable for recycling. The thermos cup fully complies with the International Quality Standard EN12546-1:2000. Thanks to its compact size, the thermos cup fits in car cup holders and bicycle holders. The ergonomic shape adds convenience when holding the thermos cup in hand. The stylish NS-402 thermos cup with a long service life is a trendy eco-friendly alternative to disposable cups.
