I like this necklace, but it is large and heavy. It's beautiful and very secure when closed, but when opened, the doors are wobbly. It opens from the center, and the two little things you see on the side are the hinges. They are very loose. It has a large center space, though, for a decent-sized picture. The magnets that hold the doors closed are strong enough to keep it closed. Overall, a very unique product.
