Mass producers make use of machines to drill holes into clam shells (which are NOT Puka shells). Clam shells are in abundance at the beaches. These imitated shells are squarish in shape, and manual holes are drilled into them. Clam shells also do not have the spiral finish on the inside, like Puka shells do. The necklaces made out of clam shells fade out and become dull after a period. Necklaces made out of puka retain their original color and texture.
