This product is ideal for homes with pets, small children, or elderly individuals who require restricted movement, such as for safely locking doors. - Brand: Richell - Quantity: Set of 2 automatic door locks I purchased extra and stored them at home, but I no longer need them. Although unused, my children took them out of the packaging and played with them a bit. The packaging has some dirt and scratches. Please check the photos. Please confirm that this is a used item before purchasing. * Shipping via Yu-Yu Mercari service in an envelope is planned.
