This time, I am selling it because my children have outgrown it. Although it was used by two children for 2 years, the frequency of use was low, and while there are some scratches due to normal use, it is in a clean condition, in my amateur opinion. Please check the images for the detailed condition. If you have any concerns, please let me know in the comments, and I will respond by adding more images, etc. Before listing, I have soaked and washed the cushions, and wiped down the main body and base, so you can use the product immediately after receiving it. 【Shipping】 I will use simple packaging with cushioning material and packing wrap, and I plan to ship via Rakuraku Mercari Bin (Kuroneko Yamato). The items in the images are all that are included. Thank you for your understanding, including the above condition and home storage.
