EarthLust bottles are hand made from high quality #304 (18/8) food grade stainless steel, which is naturally safe unlined. Our bottles are a custom design – not stock bottles. Most of our line is limited edition – new art will arrive soon! We use non-toxic paints and BPA-free safe polypropylene #5 caps. Select from our 600 ml and 1 litre sizes. Each bottle comes with a high quality carabineer and optional sports tops are available for all sizes.
