These fit the Simple Human cans very well. But, that are much more expensive than the generic ones we can get at the supermarket.

My biggest concern is that they are not biodegradable, so they will stay in our landfill as plastic for a very long time.

Please, biodegradable or combustible, would be much preferable. Price wise, these liners fall in-between the super-cheap liners (8¢ each) and combustible liners at 36¢ or 40¢ each.
