Strong and Stretchy clear elastic on 10 meter spools. Suitable for bead threading, bracelet making and jewellery repairs. Easy to use, solid elastic cord that does not fray. Hard to break / easy to tie. We recommend using a surgeons knot or Reef knot to secure the end. Add a blob of clear jewelley glue or even clear nail varnish to prevent the knot from unraveling. Transparent appearance is perfect for use with glass or other clear beads. Invisible once threaded. Water resistant. Can be worn whilst swimming and showering.
