Eyeglass straps are a great way to keep track of your glasses. They are very lightweight, but durable. Our eyeglass straps are made with quality glass or Swarovski Crystal beads and Sterling Silver and/or stainless steel beads and findings, as indicated on each individual description. They are strung on durable, but very flexible bead wire to ensure lasting quality. Each eyeglass strap ranges in length from 25" to 29", depending on the style--the length of each one is mentioned in the description. If you can't find what you are looking for, or need a different length, please contact us.
