4.2 PBT Keycaps

The keyboard is equipped with durable PBT double-shot keycaps. These keycaps are resistant to shine, oil buildup, and wear, ensuring legends remain crisp and the textured surface stays dry over extended use.

4.3 Cleaning

• Use a soft, dry cloth to wipe the keyboard surface.
• For deeper cleaning, use a can of compressed air to remove dust and debris from between keycaps.
• Keycaps can be removed for thorough cleaning using the keycap puller. Clean with mild soap and water, then ensure they are completely dry before reattaching.

4.4 Gasket Structure

The keyboard features a gasket-mounted structure with multi-layer dampening materials. This design contributes to a softer typing feel and a deeper, more satisfying sound profile. No specific user maintenance is required for the gasket structure itself.
