Duncan Toys Company was founded by Donald F. Duncan in 1929 in Ohio. Joint Custody was founded in 2010 in Washington, DC. It was only a matter of time, 93 years to be exact, before these two great companies came together to bring you what is surely the best looking and designed yo-yo of all time. It spins, it sleeps, it fits in your pocket. If you are a fan of independent vintage and record stores and Depression-era toy companies, then this is for you. These Joint Custody X Duncan yo-yos are limited and rare, a cool and functional collectible for children and adults alike.
