Plastic Vials for Spider and Arachnid Collectors

Collect. Organize. Preserve. Display.

Spider and arachnid enthusiasts need containers that show the specimen clearly and keep it protected. Whether you are collecting in the field, breeding at home, or building a display, Thornton Plastics clear plastic vials give you a clear view and a secure closure in sizes that fit everything from slings to adult tarantulas.

Our crystal-clear polystyrene vials are the same vials used by educators, museums, and researchers, and they have become a favorite of spider collectors, tarantula keepers, and breeders across the country.
