If I'm not mistaken, your bracelet is Chinese and the motif you show in the photos are of bats. These are symbolic of good luck, particularly if there are five of them. (You might want to count them!) The Chinese character for bat is "fu" and so is the Chinese character for luck. Five bats together are symbolic of the five types of happiness: wealth, long life, peace, cultivation of virtue (or good health), and a good death.
