These keycaps use standard MX-style stems, making them compatible with the vast majority of mechanical keyboards on the market. Please ensure your keyboard layout matches the set's included keys before purchasing.
The set utilizes a combination of double-shot molding and UV printing to ensure the legends remain crisp and legible. While double-shot plastic is inherently permanent, the UV-printed elements are designed to withstand standard daily use.
No, this product is a keycap set only. You will need to provide your own mechanical keyboard to install these keys.
These keycaps are 1.5mm thick, which is the industry standard for high-quality ABS sets. This thickness provides a solid, satisfying sound profile and a sturdy feel under your fingertips.
