I'm selling this item because I've never worn it. It's made of a soft, comfortable material. Please refer to the photos for the size and material. Although it's new and unused, it has been stored at home. Please refrain from purchasing if you are sensitive to this. If you have any questions, please leave a comment. Regarding shipping: I will fold the item and use recycled packaging materials for simple packaging, and ship via Mercari. If you have a preferred shipping method, please contact me immediately after purchase.
