Knockaround BIO-BASED Premiums utilize an innovative, new plastic that is created from easily renewable, non-genetically modified castor plants. The resulting sunglasses are durable, lightweight, and 53% plant-based. Packaged in a 100% cotton pouch, each pair comes with a plantable Knockaround insert card. Just plant the card, water it, and wait for the sprouts. Note: because of the bio-based material, these Premiums will fit a bit looser compared to standard Premiums.
