I have to say I was very surprised at their durability. When I first opened the box I thought oh my god what a waste of dollars and shipping - they are too flimsy! THEN - I tried them. Not bad at all :) I double pack heavy meds and use one bag for lighter stuff. If you throw away heavy items like glass or sharp objects, throw your reusable bag in the landfill (if you have to do it yourself) and stop throwing away plastic. Try these things. You may need to change the way you handle litter and although they are double bagged they are cheaper than the heavier plastic bags we throw away. change is good. Now if only someone could make STRONG compostable bags that would last long enough to end up in a landfill.
