I have two trash cans and use two different liners ("N" and "L"). These trash can liners are strong and are a perfect fit for the cans. They are not see through and I have never seen them rip due to heavy garbage. I could purchase a cheaper liner but those liners don't function like the "N" or "L". Once you tie the liner closed it will not open - any odors stay inside. I will be a lifetime user of these really wonderful liners.
