When thinking about hawaiian wedding favors, don't forget the leis luau party supplies. Not actual leis, that get tossed after your party, but mint tins that are used all of the time. Personalized with the name of the bride and groom each tin is filled with mints, sealed, and topped with a custom label.
The "Palm" size tin measures 2.25"w x 1.75"h x .5" deep and weighs about 1 oz.
