60% HHKB Plate Foam

MKUltra Corporation

Regular price $10.00

Cut from premium grade EVA foam, these foam mats are designed to sit between your top plate and PCB. They are 4mm thick and with a standard 1.5mm plate, they will compress about 10% to create a single composite sandwich.

Guaranteed to reduce rattles, vibrations and dampen the sound of keystrokes. It makes bad switches sound good and fake switches sound real. It will increase hair growth in places you want it and eliminate hair where you don't. If you don't feel 10 feet tall while typing on a keyboard with this foam inside, why, you're the one who's defective and should be returned for your own money back!

No sharks were harmed in the making of these plates.

** Important Information Regarding Foam **

If you select Black 4mm foam, you will be sent BLUE 4mm foam. Black 4mm is currently unavailable and no estimate on when it will be restocked. The blue foam is the correct thickness and even more dense so should be considered an upgrade.

60% HHKB Plate Foam


ye its pretty good man!

Kbdfans Tofu HHKB

The plate foam did a wonderful job filling in the hollow spaces/gap in between the plate and the pcb, thus removing the 'hollow' sound effect which I personally had experienced before this. Adding this with the case foam is truly a night and day experience for me, it made the case felt really solid and it elevates the typing experience & sound. Thank you MkUltra!

Side note: Kbdfans Tofu HHKB case owners should really give it a try, it works!

Exactly what I was looking for

Foam is well cut and works as you'd imagine

Great guy. Great foam.

Absolutely perfect for my m60a build. Noise dampens and makes my keyboard sound that much better. At first I initially ordered the wrong layout, but I contacted mkultra on discord and they changed it and refunded the difference! Great product, will buy again!

Way too thick

Also too expensive for what it is, especially with €30 import fees on top of it
