Purchased at the local stadium several years ago. Stored at home after being used a few times. There are traces of the product sticker on the underside of the brim. It's a free size that can be adjusted with Velcro. With the C mark as a single point, it can be used without any discomfort even at Carp games. Shipping will be done in a way that fits in A4 size, so thank you for your understanding.
