Ivory washable silk haneri (half-collar), perfect for kimono. - Brand: Sodo Idea, Soino Michi Co., Ltd. - Color: Ivory - Material: Probably silk and synthetic fiber - Features: Washable silk Thank you for viewing. This is a sewn collar removed from a nagajuban (undershirt). It's a convenient item that can be sewn onto a nagajuban like a haneri, or used on its own with beauty lingerie, etc. There was some wear on the collar, so I hand-washed it with neutral detergent (unscented) & unscented fabric softener. I haven't ironed it. The marks are less noticeable, but there are faint stains on both sides, so I hope it can be used by someone who can clean it or doesn't mind them. There is no material indication, but I think the outer collar is from the washable silk series (based on a layman's burn test...). It's a slightly yellowish off-white or ivory color, not pure white. I think it's a haneri with a different, more refined luster than the pure white, shiny synthetic fiber ones I'm selling separately. It will be folded compactly for storage and shipped in an envelope, as shown in the last image. Thank you.
