Our pouches are made from ocean-bound plastic removed from waterways leading to our oceans, combined with renewable plant-based materials. As you'll notice, we have also removed the zipper seal (let's be honest, it never really works anyways) to reduce the amount of wasteful material used. We recommend storing in a container or sealing it with a clip after opening. With each purchase, you are doing a small part in helping save the oceans and preserve our beautiful Earth.
