Amazon カスタマー 3 I bought these because they looked similar to another brand I buy that has bags that break down in a compost. They are ecologically friendly. When I received these and examined the package I was surprised to discover that the only thing that makes them ecologically friendly was the recycled cardboard packaging.These are just plastic bags. I don't want to throw out more plastic and I hope anyone buying a product labeled Eco would feel the same.
