Selling drumsticks in original packaging from Casio. 
The Casio SS-1 Sound Sticks are a rare accessory for Casio keyboards from the late 1980s and early 1990s. They act as a controller to trigger drum sounds directly via drumsticks when connected to a keyboard with the appropriate input (for example the Casio MT-520 or MT-500).
Compatibility: They are designed for Casio devices with a dedicated drumstick input.
Sound character: The sticks produce the typical "80s cheese" sound and are often sought today for retro music performances or as collector's items.
