PBTfans Klein Blue R3 — ABS Doubleshot Cherry Profile Keycap Set in International Klein Blue

International Klein Blue translated to your keyboard. Semi-transparent ABS with doubleshot legends in Cherry profile — the third round of a celebrated set built around Yves Klein's signature ultramarine.

Semi-Transparent ABS Cherry Profile Doubleshot Legends

PBTfans Klein Blue R3 — A Tribute to Yves Klein's International Klein Blue

The PBTfans Klein Blue R3 keycap set takes its colour from International Klein Blue (IKB) — the unique ultramarine born from one of the greatest artists in history, Yves Klein. A French artist and a key figure in post-war European art, Klein was a leading member of the Nouveau Réalisme movement founded in 1960 by art critic Pierre Restany, a pioneer in performance art, and a forerunner of minimal art.

More than half a century after its birth, IKB still reads the same: a minimalist vibe and a visual impact that comes from a heavy reliance on ultramarine. This is the third round (R3) of PBTfans' Klein Blue set — built in semi-transparent ABS with doubleshot legends in Cherry profile, so the colour and the legends are part of the cap, not printed onto it.

Friendly reminder: Only the keycaps are included — keyboard not included.

Key Features of the PBTfans Klein Blue R3 Set

01

International Klein Blue

The colour Yves Klein patented in 1960 — a heavily ultramarine-based blue that reads minimalist, bold, and instantly recognisable. Half a century later it still carries the same visual impact.

02

Semi-Transparent ABS

The set is moulded in semi-transparent ABS — a different feel from the usual opaque PBT, with subtle depth visible through the cap walls under direct light.

03

Doubleshot Legends

Legends are doubleshot, not printed or dye-subbed — the legend colour is a separate moulded layer that physically extends through the cap. They will not wear off, ever.

04

Cherry Profile

Sculpted Cherry profile with each row at a different height for a comfortable typing arc — the standard shape for custom enthusiast keycap sets.

05

R3 — Third Round of a Classic

Klein Blue is one of PBTfans' returning fan-favourite sets. R3 marks the third round — bringing the same ultramarine palette back for builders who missed earlier runs or want a fresh kit.

06

MX-Compatible

Fits Cherry MX switches and MX-style clones — Gateron, Kailh, Akko, and most Hall Effect MX-clone stems. Confirm your keyboard's layout matches the kits you order.

Cap Detail

Doubleshot Cherry Caps in Semi-Transparent ABS

Up close, the doubleshot construction shows: Klein Blue legends are physically moulded through each cap rather than printed on top. The semi-transparent ABS picks up subtle light through the wall, giving the set a slightly different visual weight than typical opaque PBT.

Surface texture stays smooth and uniform — the shape and feel are pure Cherry profile.

Packaging

A Box That Reads Like Klein's Own Work

The cover is a single sheet of solid International Klein Blue with a small white stairway emerging from the bottom-left corner — minimalist, deliberate, and sitting comfortably alongside the artist's own visual language.

Inside, the keycaps sit in an ABS tray. The cover is the kind of thing builders keep on the shelf next to the keyboard — part of the collection rather than packaging to throw away.

PBTfans Klein Blue R3 FAQ

What is the PBTfans Klein Blue R3 keycap set?
A Cherry-profile, semi-transparent ABS doubleshot keycap set produced by PBTfans, built around International Klein Blue — Yves Klein's signature ultramarine. R3 is the third round of the set.
What is International Klein Blue (IKB)?
International Klein Blue is a deep ultramarine blue developed and patented by French artist Yves Klein in 1960. Klein was a key figure in post-war European art, a leading member of the Nouveau Réalisme movement, and a forerunner of minimal art. IKB became one of the most recognisable single-colour palettes of the 20th century — minimalist in vibe, bold in visual impact.
What does R3 mean? How is it different from R1 / R2?
R3 stands for "Round 3" — the third production run of PBTfans' Klein Blue set. The colour palette and design are consistent with previous rounds; this run brings the set back for builders who missed it earlier.
How is ABS doubleshot different from PBTfans' dye-sub PBT sets?
ABS doubleshot uses two separately moulded layers — one for the cap body, one for the legends — fused together so the legend colour is physically part of the cap. Legends will never fade. The semi-transparent ABS used here also has a slightly different surface and weight feel compared to PBTfans' opaque PBT dye-sub sets. Sound profile differs too — ABS tends toward a slightly higher-pitched, smoother note than PBT.
Will these keycaps fit my keyboard?
Compatible with Cherry MX switches and MX-style clones — Gateron, Kailh, Akko, and most Hall Effect MX-clone stems. Confirm the kit you order covers your keyboard's layout, especially for non-standard split, HHKB, or 40% boards.
Is a keyboard included with the set?
No — this listing is for the keycaps only. Keyboard not included. The keyboards in the photos are shown for reference.
Is this one of the best blue keycap sets for a minimalist build?
The Klein Blue set is one of the more recognisable blue ABS doubleshot Cherry-profile sets in the enthusiast market — the IKB palette gives it a clean, gallery-ready presence that pairs well with white, silver, or transparent keyboard cases. A strong pick for minimalist desk setups where the keyboard reads as a piece of design rather than a peripheral.
