These are what are called for to use in the 6L semi round can I got but they do not fit snugly at the top of the can insert, so I have to mess with it every time to make it disappear at the top of the can. I buy these bags specifically to fit the can I buy because they look so neat when they fit properly and they don't slip down when you throw something in the can. These were a big disappointment in this instance.
