For Macbook Pro late 2008 to 2013 (these models had DVD drives)

MacBook Pro replacement keyboard Key Plunger / Spring / Nipple

This plunger is used underneath the key to raise the key back up after it has been pressed.

The plunger pictured is for the number and letter keys but if you need a plunger for any other keys on the keyboard just let me know at time of purchase

If you need the white clips they are also available in my shop.
