Each set includes 24 Choc Spacers. They are thin inserts placed between the switch stem and keycap to create a small amount of extra clearance.
They are useful when certain Choc keycap and switch combinations bottom out too early or touch in an unwanted way, especially in silent low-profile builds. Smaller split keyboards like the Corne and Piantor typically need 2 sets, while larger boards like the Sofle usually need 3 sets.
