I bought this several years ago during a trip to Laos. I believe the material is cotton, but I'm not entirely sure. It's a simple, rustic thread with a rough, almost basting-stitch feel. Please wrap it around your wrist, holding your wishes and thoughts. I have several of the same item. If you'd like to purchase multiple, please let me know. The fourth image is a reference photo. Local people wore them bundled together like this.
