Ocean Firework Starfish

From the Manufacturer:

Our Firework Starfishes are bioluminescent habitants of the Night Ocean. They use the light to find their way through the dark and to communicate with other living creatures. Most beautiful fireworks will lighten around the Starfishes that found their love! All our glass beads are made with the highest quality glass, sourced from all over the world. All our beads have a silver core with a 5 mm hole that fits all European bead brands. Our cores are marked with E925. This logo stands for Elfbeads and sterling silver925. If you want to be sure if your bead is an original Elfbeads, you can check the logo in the core.
