There are nearly-opaque, not stretchy, plastic bags that rips apart with something as blunt as an empty box corner, dropped - not forced into the bag. I dropped an old cereal box in the otherwise empty bag while I was holding it and it ripped from top to bottom where the corner touched. Worthless.Turns out these are "can liners" not "trash bags", and there's a huge difference! Can liners are for lightweight, non-sharp, office use. Trash bags can actually hold sharp and heavy items; and that is NOT what these bags are. I'm having trouble returning them since I was just beyond the 30 days for changing my mind - which I hope doesn't apply to receiving something different than what was described.
