for Garbage Bags
If garbage bags slips down:
If your garbage bags slip down on the inside of the can every time you try to put more trash in then use binder clips.
You can take binder clips (the black or colored clips with silver bars that you get in office supply stores) and use two clips, one on each side on the garbage can rim, clipping the bag to the can. Then flip the bars down. Now you are able to close the lid and secure the bag.
