## Description

😎The sound absorber you've been waiting for. 😎The main ingredient is high-end memory foam made in Korea. This is a sound absorber that completely blocks the keyboard from echo noise.😎It is fitted to a typical 104-key-full keyboard size. Depending on the shape of the lower part of the case, you can just put it in whole or cut and put it in.😎It is basically 0.4 inches thick, but because of its good compression ratio, it is possible to work on almost any keyboard.😎Due to the nature of memory foam materials, exposure to air can change color yellow and have no problem with function, so it is not a product defect.

Review: Essential addition to your keyboard! - This foam is amazing. The quality is great; very dense and plush. It's very easy to mold and fit into your keyboard case, and once you have it installed, it can DRASTICALLY change how your board sounds. For reference, I have a Tofu60 aluminum case, and as you can imagine, the sound was very 'pingy' before adding the foam. Once I added it, all that excess pinging was gone and I'm now able to enjoy the true sound of my lubed linear switches and stabs. Highly, highly recommend you add this to your own keyboard.
Review: Squishy, Dense, easy to work with - Really good dampening foam, best option aside from getting a price of foam custom-cut. This foam is surprisingly dense, and yet can compress nearly all the way flat to fit in odd cavities. Easy to cut, and you don't even need to cutout holes for tray-mount screws: the screws can go right through it, cutting their own holes. Board becomes slightly heavier (nice!) and sound is noticibly more muted and deep. Big enough for a full-size, and easy to trim down to size (I put it in a 96%-form factor board)

## Questions & Answers

**Q: Can it fit or work on the rk61? I want to use it on the rk61 I bought**
A: Yes

**Q: Is this available in a thinner version? there is said to be little room in my keyboard case (rk61 pro).**
A: The foam will compress a little bit but you’ll need to apply some pressure to sandwich the PCB with the case.

**Q: What are the return conditions meaning like what if I have a 60% and I need to cut to fit it in my case?**
A: You can’t just cut what you need and send back the rest.

**Q: Do you use this foam for silent any keyboard or the mostly?**
A: If you are asking if this mostly silences the noise, then yes. It doesn’t complete silence keyboards. You will get better results combining this with an aluminum case and plate.

### ⭐⭐⭐⭐⭐ Perfection
*by A***R on December 30, 2022*

I bought this foam for my custom tofu65 build. It had an aluminum plate and it sounded horrible without the foam, having a metallic sound. But, the foam was what really fixed my keyboard and made the metal sound disappear. 3 problems this foam has is that one, it is very hard to drill a hole into to screw the PCB into the case. Two, it may fry your PCB but is a pretty low chance. And three, the foam is pretty thick so it might be hard to fit the plate & PCB back into the case. But overall this foam is really solid and definitely worth it!
