Butterfly
A true icon returns in a special collaboration release. The UN x Duncan Butterfly celebrates one of the most recognized and best-selling yo-yos ever made, reimagined with custom UNKNOWN packaging and a fresh tribute to a timeless classic.
First introduced in 1958, the Butterfly helped define the wing shape design that changed yo-yo play forever. Its flared profile and wider string gap made landing tricks on the string easier than ever, opening the door for generations of players to learn classics like Trapeze, Double or Nothing, and Shoot the Moon.
Built with the same nostalgic fixed axle setup, the Butterfly delivers that authentic old school feel with short spins and simple responsive play. It is a perfect piece of yo-yo history for collectors, beginners, and anyone who appreciates the roots of modern string tricks.
An iconic design, reborn through a special collaboration.
