These lockets open from the bottom rather than the side. There is a recessed area that can be embellishes with a stone or sealed image. Inside is plenty of room for two photos, images, tiny art, etc. The brass has little patina or discoloration/spots from age and they clean up nicely.
Measures about 5/8" tall by 9/16" wide (16x14mm), not including the loop. Made in Hong Kong.
