Opened for photography, but it's new and unused. Reference price: 55,000 yen Currently (June 2025), the product specifications have been slightly changed, and the price has been updated to 66,000 yen. It seems you can customize it for yourself. It's recommended to contact a retailer and make a reservation, saying, "I received a pillow with an empty filling and would like to have it customized for myself." In that case, a maintenance card (images 7 and 8) is required. I received this from an acquaintance, so I don't know where it was purchased. If you are purchasing this (on Mercari), please check in advance with the nearest store to see if maintenance is possible.
