Description: These sea urchin shells are stunning! The natural purple displays itself on the shells through a series of bands that run from the center outward. These shells have a slightly smaller hole than the pink urchin shells so only purchase if you intend to use it with a "stem" or thin base type plant like Brachycaulos, Aeranthos, Stricta, etc.

SIZE: Approximately 2" wide by 1.5" tall
