Hello and thank you for visiting my shop!!! Made from real wine corks, these are one of a kind and handmade into wonderful necklaces. Corks are sealed with beads attached to ball chain that goes through the cork for added support. No eye screws used. Corks will vary and only the best quality is used. Beads will vary as well and will be hand selected to match your color preference. Chains are 30". These make a great gift for the person who loves wine. *Please note that excessive tugging and pulling can cause damage.
