The set (if purchased together) will convert any Klean Kanteen bottle into a stainless steel "Klean Kanteen Sippy", a smart alternative to plastic sippy cups. The adapter and Avent sippy spouts are made of pp#5 and are non-leaching and toxin-free.
Easy to clean -- just scrub it out with soap and water, or toss it in the dishwasher.
