Thank you for viewing! ● Hat: Cap, Glen check fabric ● My family member purchased this, but it seems they won't be using it after only trying it on, so I'm putting it up for sale. ● Brim length: Approximately 5.3 cm The size can be adjusted at the back (see photo 4). ● It will be shipped via Mercari delivery service (it will be shipped in a compressed state, so please reshape it as soon as possible after arrival to prevent it from losing its shape). ● Please feel free to comment if you have any questions. Color: Brown Material: Wool
