These are pretty high quality and will fit many inside round or square/rectangular shaped bathroom trashcans as a liner. When they get too soiled or too moist on the inside, just discard it for another one. It's more environmentally friendly than using plastic bags too!In my state, New Jersey, plastic bags are banned and can no longer be given out at stores, pharmacies, etc., so having these around is essential. Also, my township BURNS all trash, so these compostable bags are MUCH better with THAT in mind!Great for small clean-ups and will hold more than you think! The only thing I noticed is that you may need to be careful if you put warm/hot used coffee grinds in a paper filter inside (for example) as you MIGHT get some leakage if it sits in the bag awhile.
