Introducing the NEW Oscar Keyboards. No more broken hooks; strong, large hooks that work best with today's keys. No more masonite; made of light weight, state of the art material. New material is 1/3 the weight of a masonite board. Easily carry up to 55 keys to your vehicles using the convenient hand grip on this portable keyboard. Rows are offset so keys do not hang on top of each other. Hooks have safety catches so keys cannot accidently fall off. Size: 18 1/2" wide x 29 5/8" tall.
