Bottom line: The Razer PBT Keycap Upgrade Set: DoubleShot PBT resists the shiny wear patina ABS caps develop; main trade-off: thin font is a styling choice, not everyone's preference under RGB.

Manufacturer description

The Razer PBT Keycap Upgrade Set in Classic Black swaps your factory ABS caps for DoubleShot PBT, the material that resists the shiny wear patina that shows up on WASD and spacebar after months of daily typing. Extra-thick walls give each keypress a denser, lower-pitched sound and a firmer bottom-out than stock caps, and the DoubleShot molding means the legends are molded through rather than printed, so they stay backlight-compatible and cannot fade off the cap. Razer kept the font unusually thin for a PBT set, which reads clean under RGB instead of blocky. Compatibility is broad: the set…

Frequently Asked Questions

Will these keycaps fit my non-Razer mechanical keyboard?

Yes, if your switches use a cross-shaped stem. Razer lists compatibility with all Razer mechanical and optical keyboards plus any Cherry MX-style cross stem.

Do the legends let RGB backlighting shine through?

Yes. The DoubleShot construction molds thin, backlight-compatible fonts into the cap rather than printing them on top, so light passes through the legends.

Will these get shiny like my stock keycaps did?

That is the point of the PBT material. Razer specifies a textured PBT finish that does not wear down to a shiny surface over time, unlike typical ABS caps.

Does the set include UK layout keys?

Yes. The set includes keycaps for both Razer and standard 104/105 US and UK layouts, so the UK enter and extra key are covered.

Is this set worth it over a cheaper ABS replacement?

You are paying for DoubleShot PBT thick walls and fade-resistant legends rather than a cosmetic swap.
