This item is used to keep a door from closing completely when ventilating a room. It's inserted to fit the thickness of the door and helps adjust the gap when you don't want the door fully open. It allows you to ventilate the room while preventing too much cold air from entering and making it chilly. Made of a soft material, it comes in a beige color that easily blends with any interior. It's easy to remove, simply by inserting the doorknob into the hole in the middle. It's a cushion type that won't scratch the door.
