The Breeze Recycled Stainless Steel Carbonated Bottle - 590 ml is specifically designed for carbonated drinks that may be shaken, featuring an innovative safety valve that releases CO2 when the lid is opened, preventing liquid from spilling out. The valve also regulates pressure in high temperatures, such as when left in a car, releasing CO2 to prevent the bottle from exploding. With double-wall vacuum insulation, this bottle keeps hot drinks warm for up to 12 hours and cold drinks cool for up to 24 hours. Made from recycled stainless steel (SS 304) with a BPA-free PP lid, it has a sleek matte finish and is leakproof for everyday use. It comes in an FSC®-certified kraft gift box and is not suitable for dishwashers or microwaves.
