Build Quality

• 6063 aluminum frame with anodized or electrophoretic finish provides durability and a solid feel.
• Polycarbonate base with frosted finish reduces weight while maintaining rigidity.
• Multiple plate options including black-core FR4, aluminum, brass, polycarbonate, POM, and carbon fiber allow sound and typing feel tuning.
• Hybrid mounting system uses PORON foam gaskets for acoustic dampening and silicone grommets for flexible mounting styles, improving typing comfort and sound.
• Knobs are PVD coated brass with various finishes, mounted on aluminum supports for stability.

Typing Experience
