Resin Ocean/Beach Scallop Seashell Christmas Ornaments I use EcoPoxy brand resin, which is plant-based, biodegradable, and non-toxic. These are REAL scallop shells, which means they are not perfect, although I try my best to choose shells that are al close to perfect as they can be. ;) EACH ORNAMENT IS ONE OF A KIND! THESE ARE NOT PHOTOGRAPHS! Each scallop seashell is approximately 2" x 2" and 1/2 an inch deep. Hand-poured with resin. Threaded with twine/jute to hang. Super lightweight and ready to hang! Each of these is made to look like an aerial view of the beach/ocean. These photos are representations of the finished product - each ornament is unique and will vary slightly.
