Please understand that this item is also listed on other sites and may be suddenly removed. This is a neck warmer made with minä perhonen fabric. It can be used like a付け襟 (tsuke-eri - detachable collar). It uses choucho black fabric. Since minä perhonen fabric is used on one entire side, it's cute even when viewed from the back. The lining is made of fluffy and warm fur fabric. It has magnetic snap buttons attached, making it easy to put on. Width: Approx. 15cm Length: Approx. 77cm The distance between the snap buttons will be slightly narrower. It can be used as an adult size. Please check the length just in case. Hand washing is recommended for cleaning. This is not an official minä perhonen product or a collaboration. It is a handmade item by an amateur. I strive for careful sewing, but please only purchase if you can accept minor imperfections such as slight distortions or puckering.
