Our anatomical heart key chain may be a great way for you to symbolically give someone your heart. A hand sculpted model of the heart was produced and then a mold was made. The piece is a solid cast 3.D version of the human heart. It is made of pewter and hangs from a standard steel key ring. It comes packaged in a nice kraft box that is tied with a ribbon and includes a small card for you to write a small message. The heart is approximately 1. 5 inches tall and 1 inch wide. It has detail on all sides.
