If you have purchased a Simple Human container, then you should do yourself a favor and purchase the custom fit liners. I tried other liners and they either drop down inside the can or stick out under the lid. These fit perfectly, are thicker than others I've tried and still cost effective. And what a nice surprise it was to open the box of 400 and find that they come in convenient 20 count packages so you don't have to mess with a giant roll every time. I will buy these again!
