Safety guard to prevent outlet unplugging, easy to install and reassuring. - Brand: Richell - Product Name: Outlet Unplugging Prevention - Accessories: Mounting screws, caps - Quantity: Set of 3 - Notes: Instruction manual included (no manual for single-outlet type) Purchased about 2 years ago. One is new but has been opened and checked. The other two were used. They have been wiped with alcohol. The single-outlet type was a tape-attached type, so there is a slight stickiness remaining. Dedicated tape is not included. Spare screws and caps are also included. Not sold separately. Please understand that price reductions cannot be accommodated due to shipping costs. Thank you for looking.
