EarthLust bottles are made from high quality #304 food grade stainless steel, which is naturally safe unlined. Most of the bottles are limited edition – not stock bottles. They use non-toxic paints and BPA-free safe polypropelene #5 caps. You can choose the custom design you prefer from their 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. Every bottle helps to eliminate waste and gives you a safe and stylish way to have a cold beverage near you at all times!
