Made of pure, long-fiber mulberry silk, these gleamy black hair ties somehow manage to be tough enough to hold a ponytail during a ten-mile run, and so satin-smooth that they protect your hair from breaking, snagging, or even getting a ponytail dent. They’re both miraculous and look great with any outfit, from workout to work to dressed-up. 100% mulberry silk Set includes 4 scrunchies
