Black + Blum Isolierflasche

The high-quality stainless steel insulated bottle from black+blum impresses with its modern retro design. The bottle is the perfect companion for the office, university, hiking tours, the next trip to the swimming lake and many other leisure activities. The bottles keep drinks cold for up to 24 hours or hot for up to 10 hours. The bottles are made of pure stainless steel - The characteristic black+blum bottle neck has the thread on the inside of the bottle and therefore a smooth and convenient opening for drinking. The lid is conveniently attached to the bottle with a vegan leather strap, which is practical as a carrying loop and also means you can be sure it won't get lost. Leak-proof thanks to the tight-fitting polypropylene screw cap with silicone ring.
