Length when lowered: approximately 17 cm. Jellyfish diameter: approximately 6 cm. Pale blue aurora and tentacles. Aurora beads on nylon wire. The tentacles are of varying lengths for accent. A small amount of phosphorescent powder is used, and it glows softly when exposed to ultraviolet light. ✡ It sways and the tentacles and beads tend to get tangled, so it would be nice to use it as a car or room interior decoration.
