・ Purchased new from Amazon about a year ago. It cost around 1000 yen. Used as a cover to prevent my grandchildren and my mother, who has dementia, from pulling out the plugs. It was also useful for preventing dust. ・ It cannot be installed on outlets where screws are visible from the outside or on outlets with protrusions on the side. ・ There are no noticeable scratches, but it is a used item stored at home and has been inspected by an amateur. Please consider this before purchasing.
