This is a great dustbin. 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. If you're trying to put the bag in the can without it being visible from the outside just place the bag inside and tuck the excess between the liner and the cap of the lid. It takes a little patience at first. A great value for any kitchen, square cap plastic trash can with foot pedal has features unprecedented for a plastic can ，silent close and easy for fixing the rubbish bag. A steel-accented pedal adds durability.
