Everything is recycled, plastic-free, eco-friendly as well as Allergy-free (for those with metal allergies-Lead & Nickel free). It is very safe to wear as I have metal allergies myself. The beads are Parsley Shells, Chevron, Aa Woods, Starfish, Silk Recycled Glass & Yak Bones. Personalization is an option. You can also let me know what colors you like & dislike. If you want to change the style of the clasp or a special order, please contact us. If you have arthritis, I can add the lobster clasp which is easy to open. Free shipping is available on orders $45 or more. Teacher ID Badge Bead Necklace Lanyard, Face Mask Lanyard, Eyeglass Holder
