RETUMBLER-myTOULON GLASS is an evolution of the popular RETUMBLER-myToulon drinking bottle – now crafted from new materials. This 650 ml bottle is made from borosilicate glass, recycled stainless steel, and recycled polypropylene plastic. A standout feature of the high-quality, heat-resistant borosilicate glass is its handcrafted, mouth-blown craftsmanship. The bottle is available in clear glass or with a matt, transparent coating (similar to frosted glass). This leak-proof drinking bottle is suitable for both hot and cold beverages.
