I have always loved these shell-covered boxes commemorating someone's beach vacation.  And this one is truly exceptional!  I believe it is very RARE.  It measures approximately 6X4.5X4.25 inches.  The diorama is covered with a piece of convex plastic that allows one to explore the treasures inside.  

This vintage trinket box boasts a unique, artistic design that captures the essence of the ocean. The box is made from mixed materials and features a stunning diorama of fish and starfish, with seashells embedded in the outside of the box. It is small and squarish in shape, making it perfect for all occasions and décor styles. It's a great addition to any collection, especially those that focus on folk art or seascapes. The Victorian-style of the box adds to its considerable charm. This trinket box is a must-have for anyone looking for an amazing piece of art that also serves as a functional storage container.
