The bags arrived in a sturdy box in 4 individually wrapped packs that fit perfectly in the bag storage compartment on my Simple Human trash can. They are easy to access and easy to install and fit the can perfectly. They are sturdy and have never leaked! They are easy to remove even when crammed full. I tried using a standard 13 gallon bag and it was horrible. It was hard to install, didn’t fit. Didn’t hug the sides of the trash can. Tore the bag trying to remove it. I immediately ordered the K bags. They make changing tras bags effortless and less of a chore! I highly recommend them!
