Lot of 16 various shells - crafts, bathroom, aquarium - Lot A

This is a lot of 16 miscellaneous shells. I didn't pick these up off the beach myself, so I don't know where they came from. Please examine photos for best idea of condition. I have included photos of the measurement of the largest and the smallest shells in the lot so you can get an idea of the range of sizes. Feel free to ask questions. Sorry, no shipping Saturdays.
