This is a strong door stopper that prevents doors from opening and closing. It securely fastens with a powerful magnet and a special non-slip protective sheet. The pipe leg is easily adjustable with a one-touch up-and-down operation. Spare caps are included. I originally bought this to use on a door in a rental apartment, but I no longer need it due to a move, so I am selling it. It is unused, but the packaging shows some wear from being stored for several years. Therefore, I have listed it as having no noticeable stains or scratches. I appreciate your understanding. - Type: Door Stopper - Features: Strong stopper - How to use: Place under the door - Size: Approximately 40mm x 237mm Thank you for looking.
