I bought this in December 2024 for about 9,000 yen, thinking I would need it, but I don't seem to have many opportunities to wear it, so I'm putting it up for sale. I purchased it from Shop Channel, and according to the description at the time, it contained lamb's wool. Indeed, it's knitted with fine yarn and is warm despite being thin. It's reversible, with a delicate pattern made of three colors of yarn: gray, light brown, and light gray. The front part has a small brim. The reverse side is a solid dark gray color, knitted in a stockinette stitch, and also has a brim. I've used it three times for a short period of time. It's in near-new condition, but since it's something that goes on the head, I've marked it as "no noticeable scratches or stains." No stains, tears, or odors.
