This is a CA4LA hat. It has been used, but the material originally had a worn look, so stains are not very noticeable. However, it has been stored for a while, so it may be a bit dusty, but I think it will be fine if you wash it before use. It can be used all season! There was no size notation, but here are the measurements by an amateur: Head circumference: Approximately 56cm Brim: Approximately 4cm Height: Approximately 10cm ❗️The size is small❗️ I think it's a unisex type that can be worn by both women and men if you have a smaller head size. Since I put unworn clothes together in a box, they may have a musty smell or be wrinkled. Please understand that the price has been reduced accordingly. I am selling mainly clothes as I am decluttering. I welcome combined purchases with other items! The amount of discount may vary depending on the item, so please let me know in the comments first. Please refrain from purchasing if you are sensitive to this, as it is stored at home by an amateur. Please consider if you understand. ⭐️No pets, no smokers!
