Are they ferns or seahorses? These are woven together, topped with coralling which have all sorts of things hiding inside. Look for sea nymphs, dragonflies, fish, pearls, semi precious stones or crystals. The longer one (left image) is almost 8 inches long and is currently out of stock. You can special order these to your taste in colors, charms, glitz and more. This particular pair is here as an example of a longer fern collection variety. The other fern is about 3.5" long.
