This is a baby gate from Nihon Ikuji. It's a tension-mounted type, making installation easy. Comes with instructions. Includes extension parts. The extension parts are unused. Without extension: 73cm - 82cm With extension: 82cm - 90cm It's easy to open and close with one hand. Opens both forward and backward. The color is black, creating a calm atmosphere. There are minor scratches, and I've attached cushion tape to the parts that touch the floor to prevent damage. Please refrain from purchasing if you are concerned about minor details. The small scratches are not very noticeable unless you look closely, as the color is black. Not suitable for the top of stairs, as it is dangerous. The pink tape is masking tape. I've attached it to prevent the gate from opening unintentionally. I have another of the same product. Please inquire if you would like to purchase two. Direct transactions are also possible. Please contact me.
