These are clean, dry, empty shellls. They still have their spines attached and are a sensational way of serving starter courses. Yes, the spines will fall off in due course, but they will give you at least a few outings if you handle them carefully. And when progressive balding finally necessitates a full scalping, you’ll still have some very attractive and unusual ramekin-type dishes. Planning a banquet? - the box of 65 shells is a steal.
