Each one of these Penny Key Rings keeps 1 plastic bottle out of the landfill! Our new Heavyweight Poly material contains 100% post-consumer recycled materials (RPET). This eco-friendly utility fabric has a heavier hand feel, is more durable, and is made consciously. This means you don't have to sacrifice style for functionality. The 4CP RPET Penny Key Ring is a pouch made for holding all your cards; whether business, credit, or rewards, it also includes a metal key ring to hold all of your keys, too.
