The ultimate recycled UltraStar, made with up to 100% Post-Consumer Recycled (PCR) Plastic. Living proof that something used can ultimately become something great again. What is PCR Plastic? Have you ever wondered what happens to the plastics you put on the curb for pickup? Now that they have been used, recycled and re-purposed - they have become 'post-consumer recycled' or PCR material. Neat!
