X-Chef reusable stainless steel straws are a beatiful alternative to plastic straws. Their rainbow color and shine are unique and fun. The straws themselves are made of food grade 304 stainless steel making them a safe alternative to plastic, single-use straws. They are a bit longer than normal straws and are designed to work well with tumblers or other 20-30oz containers. They are dishwasher safe but also include an easy to use cleaning brush if you're looking to save on electricity and water.
