Change the length of any finished necklace by adding this gorgeous 3 inch extender! Extenders are popular because of their versatility in allowing the user to quickly and easily change the length. When fully extended the necklace will become 3 inches longer and when not used the extender dangles down the back of the wearer. Hang a drop from the back as a dangling adornment. Choose among dozens of gold-filled findings for the perfect charm, pendant or drop.
