Unless you got an invite to Karen O's birthday this year, then you probably haven't had the pleasure of demolishing one of Confettisystem's gorgeous piñatas just yet. Nicholas Anderson and Julie Ho are the Brooklyn-based artists behind the label, a system which according to them, sits in that happy place between the permanent and the ephemeral—in other words fancy party playthings for adults that you can also shatter around the house the morning after. Confetti have designed a special collection of festive items for Urban Outfitters due to drop sometime over the holiday season, with everything from shiny party hats to birthday crowns to okimono ornaments. Luckily the piñatas come in three smashable sizes.
