Thank you for viewing. I purchased this on Mercari in the spring of 2024, but I haven't used it. My car doesn't support ISOFIX, so I couldn't use it and have been storing it. After purchasing on Mercari, I removed and washed and dried the fabric parts, assuming I would use it. I did not use fabric softener. After realizing I couldn't use it, I covered it with plastic. ※ When I purchased it on Mercari, it was stated that it had been "used for 3 years from 2018." ※ If you have any questions, please ask before purchasing. ※ Although I received a purchase on 12/3, the transaction was canceled due to the buyer's circumstances, so I am relisting it.
