PO-33 KO cheatsheet kit

Includes:
- A cheatsheet sticker for the back of the PO-33, which lists every button combo that can be hard to remember.
- Colored stickers for the control buttons, to help visually distinguish them from the keyboard buttons
- Stickers between the buttons to clarify the two sections, and to add icons to the right side (I at least often mix up write and play)

The stickers are made of sturdy matte vinyl, removable and can be taken off and put back on several times during initial install.
