Detachable Collars * Turtleneck (beige, Fukusuke) * High neck (black, gray, Shimamura) These are detachable collars. I use them when my neck feels cold or to balance out an outfit. They're all easy-to-coordinate colors, so I recommend them to anyone who uses them or doesn't have any. I use a different detachable collar (it's convenient. I can take it off easily to adjust when in a warm room), and I thought I probably won't have a chance to use these, which I originally bought as spares, so I'm putting them up for sale. Shipping included. No price reductions.
