I use EcoPoxy brand resin, which is plant-based, biodegradable, and non-toxic. 16 ornaments total. Each wooden ornament is 1/8" thick and between 3-4 inches wide/high. Hand-painted/hand-poured with resin. Threaded with twine/jute to hang. Plain wood on back. 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. There are 16 different designs and you'll receive 1 of each design (16 ornaments total. I have other designs available and you can order multiples of one design - check out my other listings!
