Leis are a very common gift for graduation! Its a much better alternative than the fresh flower leis, which will eventually wilt.
There are so many occasions to offer congratulations - let me know what you're celebrating and I can help customize for the event!
A few examples are Little League/Sports teams, bridal showers, baby showers/gender reveal (for a baby boy, baby girl, or even twins!), conferences and birthday parties. I add custom lettering on leis for a special touch, learn more here.
