Coral and shell pink, black and gold corals produced in Hawaiian waters are cut, polished and sent to jewelry stores. Duke Road between Waikiki, Karakoya Street and Cujo Street is crowded with large and small shops selling all kinds of jewelry. Maui diving equipment factory in downtown Honolulu has a free hotel shuttle bus, which is convenient for tourists to visit their factory. This trip is free. The final arrangement is to let tourists visit a big exhibition hall, or I should say a big shop, which is undoubtedly a clever business means.

Surprisingly, not all shells are as common as those on Hawaiian beaches. Shells are often used to make flower chains. They are not flower chains made of flowers, but come from Ni Hao Island, which is called "Forbidden Island". They are made of thousands of small shells and are worth thousands of dollars. Kona coffee, which once enjoyed a high reputation for food, is now popular again. Coffee beans can be bought in many coffee plantations on the coast of Kona. Most strange food stores and coffee shops carefully select raw materials, so food and coffee taste very good. Macadamia nuts are sold from ABC thrift stores to Walworth chain stores. As long as you put on an Aloha shirt or a slim skirt, you will become a real Hawaiian.
