When you open up this locket, two discs unfold to reveal many different spaces inside the locket to place photos or keepsakes. The front of the locket features a Small print of my original Blue Hummingbird painting. This print is encased in jeweler's resin for a water-proof, glass-like finish. The print is 16mm in diameter and the locket itself is 24mm (1 inch) in diameter. It opens from the top and has two spring-loaded picture frames.
