This keyboard is a custom mechanical one that is lubed and composed of many different parts. The base of the keyboard has a similar design to a gk61. The switches that are in the keyboard are the Custom Halo Clear Switches from Drop. The keycaps that are utilized are PTB Double Shot style which contains extra layers of plastic to enhance the quality. I also lubed the switches with Krytox 205g on the keyboard so they are extremely smooth to type on. And of course, the board is RGB enhanced. Shipped with USPS Priority Mail.
