Overview

The Razer Doubleshot PBT Keycap Upgrade Set in Green addresses the two most common complaints about stock ABS keycaps: legends that wear off under heavy use and a surface that develops a greasy shine over time. The doubleshot manufacturing process permanently solves the legend problem — characters are molded from a separate plastic layer fused into the keycap body, making abrasion-based wear mechanically impossible. The PBT material addresses the surface degradation problem through its inherent density and oil resistance, maintaining a consistent matte-textured feel that ABS cannot sustain through comparable use cycles. The extra-thick walls add a third improvement: a more rigid, acoustically denser keystroke that most typists describe as a meaningful upgrade from the hollow feel of thinner ABS caps.

The 120-keycap set covers Razer's full mechanical and optical keyboard range as well as any MX cross-axis switch, spanning full-size 104-key, TKL, and mini form factors in US and UK layouts. The green colorway is tuned to complement Razer's product line aesthetic — it's a saturated, mid-tone green that pairs directly with the brand's signature accent color. Backlight compatibility is maintained through a thin, precisely spaced font that allows per-key RGB to read through the legend window clearly. Included stabilizers support the swap without requiring separate accessories for Razer boards. For builders prioritizing long-term durability and consistent feel over maximum RGB saturation, doubleshot PBT is the correct material specification — and this set executes it at a practical price point.

Pros & Cons

👍 Pros

  • Doubleshot construction makes legend wear physically impossible — the character is a molded plastic insert, not a coating, so it survives indefinitely regardless of typing volume or cleaning frequency.
  • PBT material resists the oil-induced shiny buildup that degrades ABS keycaps within months — the textured surface maintains its feel through extended daily use in a way ABS cannot match.
  • Extra-thick key walls add meaningful rigidity, producing a denser sound profile and a more stable feel on keystroke compared to standard-thickness keycaps.
  • The 120-keycap count plus included stabilizers covers full-size, TKL, and Razer Mini layouts with standard MX cross-axis compatibility, making this set usable across a broad range of existing keyboards.
  • Backlight-compatible thin fonts allow RGB to read clearly through the legend window without sacrificing the clean, minimal aesthetic of the typeface.

👎 Cons

  • PBT's higher density and opacity reduce RGB side-glow and lateral light diffusion compared to ABS pudding keycaps — if per-key underglow saturation is your priority, doubleshot PBT is not the right material choice.
  • The green colorway is a deliberate aesthetic statement — it coordinates with Razer's green-accented branding but may not integrate cleanly into builds with different color schemes or neutral setups.
  • At 120 keycaps, non-standard bottom-row layouts may have gaps — users with unusual modifier sizing should verify coverage before purchasing, particularly for 65% or 75% form factors not explicitly listed in compatibility.
  • The included stabilizers are sized for Razer's switch footprint — users installing on third-party boards should confirm stabilizer compatibility independently.

Frequently Asked Questions

Doubleshot keycaps are manufactured by injection-molding two separate layers of plastic — one for the legend, one for the keycap body — and fusing them together. The legend is a physical plastic insert, not a print or laser engraving on the surface, which means it is mechanically impossible for it to wear off. This is the most durable legend construction available for keycaps.
PBT (polybutylene terephthalate) is denser, harder, and more resistant to surface degradation from finger oils than ABS. ABS keycaps develop a noticeable shiny glaze on high-contact keys within months of heavy use. PBT keycaps resist this significantly longer and maintain a consistent matte-textured feel, which most typists and gamers prefer for sustained sessions.
Thicker walls increase keycap rigidity, which translates to a more solid, less hollow sound on each keystroke and a firmer feel on key press. The acoustic difference compared to thin ABS keycaps is noticeable — PBT with extra-thick walls tends toward a deeper, less high-pitched sound profile that many typists find more satisfying.
Yes. The doubleshot process creates legends from a semi-translucent plastic layer, allowing backlight to pass through cleanly. The thin font used in this set is specifically designed to maximize light transmission through the legend window without spreading or blurring the character outline.
The set is compatible with any switch using a cross-shaped (MX-style) stem axis — not just Razer keyboards. Razer confirms compatibility with standard 104/105 key US and UK layouts. Verify your bottom-row modifier key sizing before purchasing, as non-standard layouts may require substitutions from the 120-keycap selection.
