Fruit Seed Keychain - Always Smiling - Bird Whistle

Fruit Seed Keychain - Always Smiling. Below is a macadamia nut fruit, carefully carved and meticulously cleaned inside with tweezers. With a little practice, it can produce a surprisingly loud sound, even imitating bird calls for use as a bird whistle, played similarly to a flute. The hat on top is made from the acorn cup of a red oak. The fruit above is an acorn from an evergreen oak, a native Taiwanese acorn, beloved by the Formosan black bear and dinosaur toys alike. This keychain is not only charming and symbolic but also functional as a whistle, making it an ideal choice for gifts or personal use. Its hard exterior will develop a beautiful sheen with wear.
