YIMAGUJRX Sound Dampening Foam for Mechanical Keyboard Bottom, Made of YM40-Sponge (10mm Thick)
A full-layout sheet of YIMAGUJRX YM40 nanosponge, a softer alternative to Poron for filling empty space in a keyboard. It is trimmed with scissors and comes with a pry bar.
Price range: See on Amazon
What we liked
- + High-porosity nanosponge that the listing describes as softer than Poron with strong sound absorption
- + One sheet of about 42.8 x 12.4cm can be cut for 61 through 108 key layouts
- + Plastic pry bar included for opening the keyboard case
Trade-offs
- - Thickness is unclear: the title says 10mm while the size line lists 0.3cm, so confirm before ordering
- - Sold as bottom foam, so using it between plate and PCB means cutting switch openings yourself
