This listing is for one (1) Layershift wrench.
Easiest way to mod sticks with screw-buttons. We no longer need to cram our fingers around the screw-buttons to twist it in/out. This tool does all the heavy lifting and makes swapping and securing buttons easy and fast! It should also be noted that buttons are tighter and more reliably secured than if done by hand.
This is the 30mm wrench used for Seimitsu PS14GN/KN buttons. You do not need to purchase multiple wrenches for each button. One will do!
