Poron Dampener Kit

The kit includes 3 pieces of poron dampeners below:

  • Plate Dampener between PCB and plate
  • Switch Dampener between plate and switches
  • PCB Dampener under PCB

We suggest using poron dampeners with PC plate (Default) for best results.

Plate & Switch Integrated Foam

  • Made of supercritical foaming material, it will make the overall dampening system more stable and helps to make typing sound better. 

We suggest using integrated foam with Aluminum plate (Add-ons) for best results 

Gasket Slips

  • Gasket slip design, easier to install
  • Strong stability, very durable and can keep original flex after long-time usage
  • Density between Poron and silicone. 

There are three kinds of gasket slips by default, they have different stiffness and users can choose anyone they like. Wuque studio will keep stocking the gasket slips and also welcome other board designers to use them.  

Prism External Weights and Accent Lines 

Prism External Weights and Accent Linesature of the treatment process, all prism colored PVD accent lines and external weights will have purple, yellow, blue, and other colors' in a random gradient. This is difficult to be controlled. While we will try our best to make them look similar to our rendersprism prototypes , please understand that there may still be differences with the final product. Variations due to this process are within our quality standard.
