I am selling this item, which I purchased for around 3000 yen in August of this year and used for less than a month before my child finished potty training. As shown in the fifth picture, a screwdriver is periodically needed, but I lost the screwdriver during assembly. I used a 10-yen coin when the screws became loose. Instructions, stickers, and screwdriver are not included. ※ I strive for smooth transactions for both parties, so please be sure to check my profile before purchasing. ※ Please understand that this is a used item. Also, please be aware that there may be scratches, stains, or fraying due to my amateur inspection. Please understand this as well. Please consider purchasing with this understanding. I will pack the item compactly for shipping. I welcome combined purchases with other items! Please feel free to negotiate the price! I have two preschool-aged children, so please understand that it may take a few days to ship the item.
