These are the best trash bags that we've ever used. No more having to double bag the trash lest it rip through the bag. These bags are REALLY HEAVY plastic. And, the 42 gal. size is handy. We use our own custom length twist ties though, not the ones that come with these bags. The bags are so thick that we find that a longer twist tie works better. We buy spools of green, plastic-coated wire with a self-cutter to use as twist ties.
