Comments on Durock Sea Glass switches | Comments on HMX x 80 Retros FJ400 switches |
Durock Sea Glass Switches are multi-colored switches which resemble vibrant sea glass found on beaches. Utilizing Durock's blend of nylon and UPE, these switches are smooth especially when paired with their updated P3+ stem – divinikey. The Sea Glass Series are one of the smoothest stock linears with Polymer Nylon & UPE Blend Housing and P3+ stem. High-precision molds to minimize housing and stem wobble. Specially made 62g spring for soft typing and noise reduction. Lubricated with the latest advanced lubricant application. These switches will come in a random mixture of 5 pastel sea glass colors – beaverkeys. | The switch color scheme is inspired by the Fuji 400 film roll. Compared to traditional HMX clicky switches, this switch has a more thocky sound. It features an HMX T2 material stem, P2 material bottom housing, and a PC material top housing that dampens the sound. With a total travel of 3.8mm, the sound is quieter compared to the 3.5mm travel switches – Deskhero. |
