The OEM keycap profile features a slightly curved design with a higher height compared to other profiles. This design provides a comfortable typing experience, with the curved shape conforming to the natural curvature of the fingers. The keycaps are typically made from ABS or PBT plastic, which is a durable and long-lasting material that resists wear and tear.

One of the main advantages of OEM keycaps is their compatibility with a wide range of keyboards and switches. They are used by many major keyboard manufacturers and are compatible with Cherry MX-style switches, which are widely used in mechanical keyboards. This makes it easy to find replacement keycaps or to customize the keyboard with different color schemes and designs.

Overall, OEM keycaps are a popular choice among keyboard enthusiasts and gamers due to their comfort, durability, and compatibility with a wide range of keyboards and switches. They provide a classic and versatile look that can be customized according to the user’s preferences.
