These bulk shells for sale are called Elegant Dosinias and can make the most stunning shell pendants or nautical decor. Atlantic Semele (not pictured) is a little more domed and rounded. These come in a pack of three shells. They range from the length of a pinky to the size of your palm. They are rare, so handle these with care. A good polishing, buffing, and clear coat will make these ready for display!
