I was concerned with how a full bag would hold itself, not anymore. It took me maybe 20 seconds to figure out how to tie them, and they are definitely durable - I have tested this well.
These bags may not have drawstrings or be quite as stuffable as regular trash bags (yuck), but there is no replacement for feeling good about what I let inside my home and what I touch. Plastic-free, BPA-free, PFAS-free, phthalate & fragrance-free, completely compostable: I searched for a good trash bag for days with multiple back-and-forth emails with 7 or 8 companies once I had narrowed my choices, no other bags come close to these. When my repurpose bags arrived I was very happy and am still happy with my decision.
Thank you to repurpose for making these an option and making me and my home healthier and cleaner.
