Know before you buy
This set is designed to dampen hollow resonance and vibrations within the keyboard case. By filling the empty space, it creates a more solid, muted typing sound and a slightly firmer feel under your fingers.
No, the included case foam is specifically engineered for the standard Discipline 65 build and is not compatible with the CFTKB acrylic case.
The 3mm plate foam is optimized specifically for the stock FR4 plate. While it may fit other plates, we cannot guarantee a perfect fit or acoustic result if you are using a custom or aftermarket plate.
No, the foam is designed to work with standard Cherry MX-style switches. You will need to remove your switches to install the plate foam, but no permanent modifications to your components are required.
The set is crafted from silicone, which is chosen for its durability and excellent acoustic dampening properties compared to standard packing foams.
