This listing is for a vintage obijime - the finishing touch for a kimono ensemble. Obijime are wound across the middle of the obi belt and tied with a decorative knot at the front.  It is a braided or woven cording, sometimes referred to as kumihimo with a color and design that complements the obi rather than matching the color. See the video below for how obijime are made.

This obijime is a formal-style flat herringbone weave with occasional pops of a bright minty green accents toward each end and in the tassels. Metallic gold threads elevate the design to provide an extra bit of elegance. 

Other contemporary uses of the obijime are as a cord belt with jeans or dress or modified into fashion accessories such as hair bands, purse straps, lanyards, glasses holders, jewelry, and more! See the video below on wearing an obijime as a casual belt, necklace, or bracelet.
