Purchased on Amazon in January 2025. I opened it intending to use it, but I no longer need it, so it's unused. I only opened the outer box, and I haven't taken the contents out of the bag, so all the parts are included. For packaging reasons, I may take it out of the box (the box will be folded and included) before shipping. I may change the shipping method to Rakuraku Mercari Delivery.
