I had this custom-made about a year ago by Himawari on Mercari. I've only used it indoors. It shows signs of use, but it's well-made, so I think it can still be used. My pet was 3.5kg. I don't have the record of the size when I ordered it, so please consider the size of the wheelchair in the photos. The height can be adjusted somewhat with the belts. I am not negotiating on the price. Thank you for your understanding.
