This is a great trashcan. For being plastic, it is well made and does the job. You can use this without a bag but I prefer a bag to be extra sanitary.

A great value for any kitchen, the slim plastic step can has features unprecedented for a plastic can ，silent close and a slide lock that helps keep the lid from being accidentally opened by kids or pets. A steel-accented pedal adds durability
