KINTO TRAVEL's double stainless steel walls with a vacuum in between prevent heat transfer. The foil layer covering the inner wall reflects the heat inwards and also stores heat and cold perfectly. Keeps drinks cold for 6 hours up to 8℃ and hot over 65℃. In addition to easy handling, the material and texture support long-term use. The container is made of robust 18-8 stainless steel and does not rust easily. The surface of the coloured mugs is powder-coated to prevent scratches. In addition, the smooth, electropolished inside is odour and stain resistant so you stay clean and fresh. Because there are no screws, the lid rests comfortably on your mouth and is designed to prevent ice cubes and hot drinks from spilling out too much, so you can drink comfortably until the last sip. The lid is leak-proof so you don't have to worry about spilling the drink. The closure with seal is made of food-grade polypropylene and silicone. Dimensions (mm): 74 (diameter) x 197 (height with cover); 173 (height without cover).
