ABS (acrylonitrile butadiene styrene) keycaps also have several benefits:

1. Cost: ABS keycaps are generally less expensive than PBT keycaps, making them a more affordable option for those on a budget.
2. Shine: ABS keycaps have a smooth surface that can develop a glossy shine over time, which some people find aesthetically pleasing.
3. Customization: ABS keycaps can be easily printed or dyed with custom designs, allowing for greater customization of the keyboard.
4. Smoothness: ABS keycaps have a smoother surface compared to PBT keycaps, which can make them feel slicker and more comfortable to type on for some people.

In summary, ABS keycaps are a more affordable and customizable option for those who prioritize these factors in their keyboard setup. However, they may not be as durable or produce the same sound and texture as PBT keycaps.
