Tomy Gearations Amusement Park Add-On Set. This add-on set works with the Tomy Gearations Board as shown. This listing is for the add-on accessory set only, but I do have the Tomy Gearations board with original gears available in another listing. See video of these gears in action on the Tomy Gearations board. Great stem/sensory learning toy for all ages! Excellent very gently used condition. Rare vintage item! Smoke & pet-free home.
