USMC Mom pendant/charm is made from 2 genuine U.S. pennies, one on top of the other, bonded together, giving the pendant a good weight. Images are then printed with high quality, fade-resistant ink and adhered to the top penny. Two generous coats of crystal clear, 2- part enamel are applied over the image for a glossy, durable topcoat. The pendant is strong, durable and waterproof. Back of pendant shows "heads". Comes complete and ready to wear on a 24-inch ball chain. The ball chain is very easily cut to size, with scissors, if you would like the necklace smaller.
