A bag hanger is a device designed to hang a bag securely on a wall or door. It usually consists of a hook or bracket that is attached to the wall or door, and a loop or clip that is attached to the bag. The hook or bracket is typically made of metal, plastic, or wood, and the loop or clip is typically made of fabric or elastic. Bag hangers are used to keep bags off the floor and out of the way, and to make them easier to access. They are often used in closets, entryways, bathrooms, and bedrooms.
