These shells are very heavy for there size. I do have some individual pictures. They are a light brownish. Not coated with anything so can go in aquarium. Perfect for mirrors, wreaths, wind chimes, picture frames, shell flowers, shell layer sculpture figures! This item is limited only by your imagination. They are natural and have slight differences in stripes and spots from one to the next ! I have tried to show that with the picture. Price is per each.
