Water never tasted so good. Simple, clean, green. Ello's Pure glass water bottles. The clarity and quality of glass meets style. Our glass bottles are annealed to give them the extra strength and durability for on-the-go use, and they exceed all FDA and California Prop65 standards (Lead & Cadmium free). Food safe silicone sleeves protect the glass and provide ample grip surface when you're on the move. The sleeve also features a triple-thick boot at the base to provide extra impact protection and the leak-proof cap has a unique double-wall construction for greater protection. The drink opening is sized to allow you to add ice, while being small enough to control the water flow to prevent over-flow spills. The whole bottle is dishwasher perfect with no need to remove the sleeve for washing. 100% BPA-Free. 20-ounce capacity.
