EarthLust bottles are made from high quality #304 food grade stainless steel, which is naturally safe unlined. All bottles are a custom design - not stock bottles. Most of their line is limited edition - so the designs are changing. They only use non-toxic paints and BPA-free safe polypropelene #5 caps. Bottles come in 13 ounce, 20 ounce and 1 liter sizes. Each bottle comes with a high quality carabineer and optional sports tops are available for the 13 and 20 ounce sizes. Earthlust is happy to bring its line of bottles to you - every bottle helps to eliminate waste and gives you a safe and stylish way to have a cold beverage near you at all times!
