Thank you for visiting our shop! (*^^*) This is a cap liner. For those who want to protect their clothes and hats from sweat and sebum stains by sticking it to the collar or inside of the hat ☆ ■Size■ 24.5 x 4cm This is a set of 10 brand new, unused liners, but the original bag has been torn, so they will be shipped in a different bag. White color is also available. Due to shipping costs, it may be lightly folded in half for packaging. We are also selling on other sites, so we may delete the listing without notice.
