Really surprise someone with a unique gift that's personalized with his or her name carved on the shell! The shells are carved on the lustrous Tiger Cowrie Shell (Cyprea tigris). Each shell is approximately 3" long, 2" wide and about 2" high. Of course, as with any natural product the size will vary slightly. Each shell has a carved nautical-themed background. The background designs vary and may not be selected. Choose from Name, Message or Zodiac Style.
