I LOVE these liners! I didn't realize a sample pack came with my new trash can for over a month, because someone else unpacked the can and tossed the package off to the side somewhere. One day, I noticed them. Hmmm... what are these? Oh! Free bag samples. Well, I'll never buy special bags, but I'll use them because they're free. I put one in and stood there looking at it in amazement. It fit like a glove and the outer edges just fell into place like magic. No struggling to get the top around the can, no trying to shove the inside of the can back into the outer part... everything just slid into place. The entire inner part was perfectly lined, allowing every part of the can to be filled, with no air pockets taking up space. I ordered my first big box of refill liners immediately.
