Imagine walking along the shoreline at low tide and discovering a carpet of these tiny, perfect shells, each one a unique splash of color. That’s the essence of this mix.

Some may have delicate patterns of stripes or dots, while others are a solid, glossy hue. Their small, top-shaped form is instantly recognizable and beloved by crafters and decorators. Each bag is a natural assortment, a unique collection gathered by the tides, ensuring that your mix is one-of-a-kind. They are cleaned and prepared, ready to bring a touch of coastal charm to your next project.

Umbonium* snails live in incredibly dense colonies, sometimes with over 1,000 individuals in a single square meter of sand.
They are known as “broadcast spawners,” releasing their eggs and sperm into the water column simultaneously, a spectacular event that relies on chance and tides.
The genus name Umbonium is derived from the Latin word umbra, meaning “shade” or “shadow,” likely referring to their habit of living in the shallow, shaded waters of the intertidal zone.
These snails have a small “trap door” or operculum, which they use to seal themselves inside their shell when threatened or exposed at low tide.
