This time, it is being sold because the children have outgrown it. Although used by two children for 2 years, the frequency of use was low, and there are some scratches due to normal use, but 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 images, etc. Before listing, the cushions were soaked and washed, and the main body and base were wiped down, so you can use the product immediately after receiving it. 【Shipping】 Simple packaging with cushioning material and packing wrap, and shipping is planned 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.
