This is a han-eri (replacement collar) for the Kirakku Nagajuban by Eriyoshi. It is for the awase (lined) season, white, and is a shiose han-eri type. It has a zipper and can be attached to the Kirakku Nagajuban. The collar is a "batchi-eri" type, folded in half. The collar core is made of bias-cut fabric, so it holds a beautiful shape. It has a very luxurious feel, similar to silk. It can be washed at home, and it is resistant to shrinking and losing its shape even after washing.
