This product is a shining example that being eco-friendly does not sacrifice quality. Review: Buy in small amounts if you don’t really sell much - I bought these and left them aside for whenever I sold a jersey. After 6 months or so (possibly less) they become weak, like a leaf. They’re great and need insane amount of force to tear the packaging when they’re fresh, so make sure you only buy what you need within three months. ## Features - 100% BIODEGRADABLE - Made of PBAT and modified corn starch in accordance with the standards of ASTM 6400, EN13432, BPI, and OK COMPOST HOME.
