Plastic is a serious problem and we want to ensure our customers refill our stainless steel bottles to keep plastic out of the system. We promote refilling, recycling, avoiding single use plastic and buying in bulk. Stainless steel is shatterproof and the most durable material to use in bottles. It is also the most recyclable material.In addition, we wanted to help create refill stations so that customers can bring bottles back to a store and refill over and over again, saving plastic waste.
