If you are unsure of which keyboard you have please click here. These parts are the individual scissor mechanisms for the Dual USB iBook and Titanium PowerBooks. These are the white plastic parts that are found under the keycaps. Small scissors are $2. Medium scissors(Caps Lock, Tab, Delete, Shift, and Return) are $5. Please note: The keyboard layout shown is for the original Titanium PowerBook. If you are ordering scissors for a later model keyboard, please order by position, not by what is on the keycap.
