This is a han-eri (collar) made of 100% polyester. It can be removed and washed at home, making it easy to care for. This is a colored han-eri, so it looks great on its own, but you can also layer it under a lace han-eri to expand your coordination options. It would also look lovely with embroidery. It will be shipped flat, folded after being taken out of the tube. If you would like the tube for storing the han-eri, please comment and we will add it for an additional 100 yen.
