Each pendant has been crafted with UV resin, real shells and sand from the Arizona desert. This wavy pendant is 2 inches long, 1 inch wide and strung from an 18 inch wax coated nylon strand. Purchasing this, you will receive this exact pendant. Pendant #4. The video shows other styles that I can make.
