This is a baby gate from Nihon Ikuji. I am selling it because my child has grown and no longer needs it. It is a set of 2. I installed them at the top and bottom of the stairs, but I didn't open and close them very often, so I don't think they show much wear. I will clean them with alcohol before shipping. Please note that the boxes are quite worn. Thank you. ※Regarding accessories (common to both)※ ⚫︎There are no original parts for screws 9 and 12. I will provide suitable replacement screws. ⚫︎The auxiliary plates (13) were not used, so they are both new. ⚫︎I have lost the instruction manual, so I will print out a downloaded version from the internet and include it. If you have any other questions, please comment. Thank you.
