Floral souvenirs, such as leis, are popular gifts to bring back from a vacation. Leis are traditional Hawaiian garlands made of flowers, leaves, shells, and other natural materials. They are often given as a sign of love, friendship, and respect. They are also used to celebrate special occasions, such as graduations, weddings, and birthdays. Leis are a great way to remember a special trip and make a lasting impression on the recipient.
