Keycap Essentials Guide
Keycap Materials: PBT vs. ABS
ABS: Offers vibrant colors and a smooth touch. However, it is softer and prone to becoming shiny/greasy over time.
Keycap Profiles: Shape and Height
XDA / DSA: Uniform height across all rows. They offer a clean, flat, and retro aesthetic but may require time to get used to.
Keycap Legends: Printing Techniques
Dye-sublimation: Ink is heat-pressed into the plastic. It allows for colorful designs and is highly resistant to wear.
