Rice Paper Confetti is water-soluble, meaning it will dissolve in water. This makes it perfect for outdoor use. ***Please note - the dissolving process is not instant and does take a lot of water and agitation. Please have your venue test the product before use.*** The rice paper confetti is also slightly thinner than typical tissue confetti, meaning you get more individual pieces of confetti per pound than you would in one pound of standard bulk confetti.
