Eternally Beautiful 

Our vision for the Sisyphus 65 was to create a visually appealing keyboard that draws inspiration from the absurdist tale of Sisyphus, a well-known ancient Greek myth. Our aim was to achieve a sophisticated design that is easily recognizable due to its uniqueness.

To pay homage to the dystopian hero, we have incorporated contoured lines on the keyboard that depict the hill and the boulder. The PVD stainless steel column represents the weight of the boulder, while the straight lines on the main part of the case top represent the hill. Moreover, we have included the Morse code "C L I M B" on the top of the keyboard, a word that is used repeatedly in the Sisyphus story. Additionally, we have used dichroic anodizing on the front of the keyboard and the metal badge to add to its charm and character.

Overall, we are confident that the Sisyphus 65 will capture your imagination and leave you enchanted with its exquisite design and attention to detail.

Difference between the prototypes and the GB products

1. Accessory name stickers The accessories of the GB version all have item name stickers. Only some accessories in the prototype have item name stickers.

2. Different laser engraving patterns on PVD surface Reason: The PVD weight of Sisyphus65 prototype used real gold electroplating process, and the pattern of radium carving showed a dark gray texture; In order to improve the wear resistance of the electroplating surface, it will be replaced with imitation gold electroplating process when GB, and finally the radium engraving showed a different appearance. After many times of communication and adjustment, the laser engraving pattern was controlled to the extent that it would not damage the electroplating surface and could be viewed clearly with the naked eye at multiple angles, and the color of the pattern turned to silver gray.


1. Possible sound problems Since Sisyphus 65’s special cylindrical counterweight props up a space at the bottom, after testing, we found vibration sounds may appear on some desktops which with special materials. As long as the bottom is padded with soft materials, such as leather pads or soft cloth that can solve this problem.

2. It may be felt that the bottom case is thin This is a structural modification that yields to the design concept. The visual performance seen from the side and the bottom wants to highlight the "ridge and boulder", that is the fusion and collision of the rectangle and the circle. The rectangle should not be too wide. For this, the thickness of the bottom case can only be reduced as much as possible.

Quality Disclaimer by Velocifire

  1. Appearance QC standards (including Stainless steel PVD weight) are as follows: According to Group Buy QC standard, our QC is in the light conditions are normal, and keep the distance between 20-25 cm to check the keyboard‘s appearance. If there is no defect then the QC check is passed. If the keyboard has problems such as dirt/spot/trachoma, as long as the dirt/spot/trachoma is less than 0.8-2.0 mm² (check with a film caliper), the QC check will pass. You can view the table of QC standards for dirt/spot/trachoma.
  2. Plating marks caused by hanging holes inside during keyboard production are normal phenomena during production.
  3. Due to the special material properties of PVD, there may be slight, unavoidable dust on the mirror surface during production. These are normal phenomena and within our quality approval range.
