Dog Wheelchair, 4-Wheel Dog Cart for Shiba Inu, Dog Wheelchair

This is a custom-ordered dog wheelchair (with chin rest) purchased from Plus One on Mercari.
It was semi-custom ordered for a Shiba Inu weighing approximately 7-8 kg whose hind legs became impaired. The purchase price was 44,000 yen. It was used for 2.5 months to relieve stress, prevent bedsores, and during mealtimes. I hesitated to buy it due to the high price, but it was very helpful for my beloved dog's care. I believe it's a product worth purchasing, so I would be happy if someone whose dog fits the size could use it. Please check the applicable sizes below and in the 6th photo (reproduced from Wheelchair Plus One).
It was only used indoors, so I believe it is in beautiful condition. However, the panda chin rest has been used and is slightly dirty (home cleaned). This is a used item and has been stored at home, so I would appreciate it if it could be passed on to someone who understands this. I work on weekdays, so shipping will be on Saturdays, Sundays, and holidays. Thank you for your understanding.
