These stabilizers are harvested from brand new, never used, vintage NOS mechanical keyboards--which means these stabilizers are also brand new, never used! They will only work as plate mounted stabilizers, so if you need PCB mounted please check our other products! The plastic used to make these is a smooth, dense type of plastic which gives a very different feel and sound than the tinny hard plastic stabilizers found in more modern keyboards.
Due to the nature of the keyboards these were harvested from, we do not have any spacebar compatible stabilizers; these will, however, work for most other standard MX keys (left shift, right shift, backspace, enter, etc). Each order is for one pair of stabilizers.
