Case of Wholesale Theodoxus Oulaniensis, the river nerite seashell for crafts measuring approximately under 1 inch.  These Theodoxus shells display variation in color and pattern, including shade of gray, white, brown, and some with distinct oblique stripes or checkered patterns.  They are typically solid and spiral- shaped, with some having a more rounded or flattened appearance.  These snails are often used by hobbyists to control algae in freshwater or brackish aquariums.

Our shells are commercial grade. All seashells sold in bulk, by the gallon and by the kilo will contain some unusable shells and there will be a little gravel in the bags!
