Original Korg button spares.
Replacement 4 button plastic molding to fit to the left and right of the LCD screen on a Korg M1 and X5d synth.
Often the switches are fine, but the plastic hinges snap and despite best attempts to repair the hinge is never ever as strong as it originally was and is prone to breaking easily again.
Replace with a new original spare part.
