This is a set of 40 assorted Purple Delphinula shells. They measure about 1 1/2" to 1 3/4" across. Super shells for any display, craft idea, etc. Natural colors and shapes! I have a few sets, so you will receive shells very similar to the ones pictured, and if you buy more than one set in the same transaction shipping will not increase! Winning bidder adds $7.50 shipping in the US.
