A han-eri (detachable collar) with a design of flowers on green and off-white stripes. The flowers peeking out from the neckline are cute. It was attached to a washable nagajuban (long undergarment) and worn several times. I have cleaned it at home each time, so I don't think there is any sebum stains. Since it was attached to the nagajuban, there are fold lines, but I think it will be very easy to attach when you put it on your own han-eri. Especially with polyester han-eri, attaching it without fold lines is, I think, a real challenge. Highly recommended for those who find attaching a han-eri troublesome. It's a rare item because the brand is no longer available. Thank you for looking. Please read the profile.
