I used this for about a year after purchase, but I'm selling it because I no longer need it due to moving. Would you like to use it to prevent children's mischief, electric shock, or fires caused by dust accumulation? Although there are no noticeable scratches or stains, please understand that this is a personal inspection. I will disinfect it with alcohol before shipping. This cover is attached to a power outlet plate to prevent children from pulling out plugs and getting electric shocks. It prevents the loss of data, such as on computers and recorders, due to the removal of power outlet plugs. You can cover the outlet while the plug is still inserted. It can also be installed on simple fire-resistant outlet plates. It has a structure that children cannot easily open. - Brand: Richell - Type: Outlet Full Cover - Set Quantity: Set of 2 - Outlets that cannot be installed: Outlets where screws are visible Thank you for viewing.
