The MXR pedal is NOT INCLUDED.  For illustration purposes, this listing includes photos that show how the slider caps look on the pedal versus the old version. 

These are made of rubber material and are pliable.

Color: white
Size (approximate): 3/8" tall
1/8" diameter (since the material is pliable, it has a bit of stretch which holds it securely when pushed onto the slider.  These fit very snugly on the slider posts for a perfect fit)

The photos that accompany this listing show the actual slider covers you will receive. 

I will ship these the same day as you order!
