2 mm Poron Case Foam

Product Description

Cuttable and versatile, this 2 mm thick foam is used between the PCB and case to reduce hollow sound, rattle, and accentuate deeper acoustics. The perforated lines correspond to 60%, 65%, and TKL layouts, so you can trim it easily for precise fitment. It’s perfect for boards that need a bit more clarity and warmth to the typing experience, or as a thocky upgrade.
