Purchased around March 2023 and used for about a year and a half. A drool cover was always used during use, so it was never put directly in the mouth. Please check the photos as there may be some pilling on the shoulder straps due to rubbing. *I am also selling a chair belt separately. Please take a look if you'd like. *Please understand that this is a used item. *There is a possibility that the shipping method will be changed from Rakuraku Mercari Bin to Yuuyu Mercari Bin or vice versa. *Please note that it may be slightly compressed for shipping. *Please note that this is a used item and may have minor scratches or stains due to amateur inspection and storage. Therefore, there may be some oversights. Please refrain from purchasing if you are concerned about minor details.
