Yes, this item is available for immediate purchase. I purchased this on Mercari. I am selling it because it didn't suit me. SIZE: 1 (Equivalent to S size) The head circumference is unknown, but when I tried it on, it was too small and wouldn't fit. I believe it's designed to be small, around 55-57cm, and should be wearable for women. This is a casquette that UVERworld's TAKUYA∞ wore in a discussion with Yu Takahashi. The same design and color are not often seen on the market, so it may be a valuable item. Feel free to comment with any questions.
