switch pack from GH

any pic???   

haha... then i think we're partner in crime 

There is 2 different type of O-rings from that seller,
both of them have same size of "hole" but different thickness,
so that can reduce range to bottoming out the keys.
The seller recommend that the Original Cherry Keys uses the small O-rings
instead of the big O-rings.

Note that the original Cherry Keys Height doesn't mean cherry switch stem keys,
most of the cherry switch key in the keyboard market,
(like Steelseries, Corsair, Razer, Leopold, Filco, Cooler Master, they all use cherry switch)
are OEM height, which mean they are "Non-Cherry-Original-Height" AKA OEM Heigh
except those that is manufactured by Cherry Corp. themselves AKA Cherry Original Height(原厂高度）

If you have a Cherry Original Keyboard, you better get the small O-rings,
if you have an OEM keyboard, you can chose the big one or the small one,
or you can have both of them, and try it out see which one you like better.
