Four ways to wear the kaesa-eri (layered collar): Enjoy it as a single layer or a double layer. It's a bat-eri (pre-shaped collar), so it's easy to use. It can be used with all types of kimono if the colors match. Made of rinzu (figured silk) with a slight sheen. The material is pure silk and is new. Collar length: approximately 128cm, width: approximately 5.8cm The images may appear slightly different in color depending on the viewing device.
