PBT Backlit Keycaps for Cherry MX Switches UK ISO QWERTY - Black


PBT (short for "polybutylene terephthalate") is one of the hardest, most durable materials for keycaps. It is more resilient against heat and chemicals than ABS, but its properties also makes it more difficult to mould, which makes it more uncommon.

Legends on PBT keys are often laser-etched or dye-sublimated but only very rarely double shot moulded. PBT does not turn yellow from exposure to ultraviolet light, like ABS does. The resilience against heat makes it a good candidate for dyeing in a hot dye bath.

Double Shot

Double-shot moulding, double-shot, dual-injection moulding, two-shot moulding or insert moulding is the process of moulding plastic around a preformed metal or plastic insert. This has been a popular process to create very durable keycaps in the past. Recently, the process has become more rare


Maximum contrast lettering: the legends are bold and vibrant and pure in tone, with smooth edges and uniform colouration.
Zero wear: the legend will never wear, as it runs right through the surface of the keycap.
Colour freedom: the keycap and legend can each be of any colour desired: this lends itself well to custom keycaps where a wide range of colours is highly desirable.
Feel: the legend and the keycap are one, and the legend cannot be felt while typing


Colour: Black
Double Shot Keys.
Material: PBT Plastic.
Backlight Compatible
Suitable for Cherry MX switches and other compatible Cherry type switches.

Great materials

Much nicer materials used for the keys than the stock corsair K70 LUX. I was replacing due to poor material issues (brittle and cracked stanchions under the keys causing the caps to pop off when touched)
The only drawbacks I've found are that the keys are very dim in comparison and the biggest issue is that the bottom row keys do not fit correctly (CTRL, ALT, WIN, SPACE etc.)
This wasn't too much of an issue as those keys from the standard set were in good enough condition to remain in place.
Very pleased with the quality of the product but also slightly surprised by the amount of packaging used and the enormous box they arrived in. I hoped they had sent me an RTX 2080 Ti by accident before the postman put it in my hand and it was light as a feather.

Good quality replacement keycaps for my Ducky One

I have the first edition of the Ducky One (the version before the One2), which came with ABS keycaps. At the time I bought the keyboard, I didn't know what this meant, and within a few months, the keys began to shine (as I have a sweaty hand problem). After about 2 years, I finally decided to replace these keycaps with PBT ones, but it was difficult to find ones for the entire keyboard (due to the extra 4 media keys in the top right). Finding this listing helped me out quite a bit.

Now I dropped a star because I wasn't quite sure which Ducky keyboards the keycap legend was intended for; a more zoomed in picture would help as well. For instance, the lower keycap legends on the numpad number keys don't light up on my keyboard simply because there is no LED there on my keyboard, while the Enter, NumpadPlus and NumpadEnter keys have very dim lighting compared to the rest of the keys, since the LED was offset to the side. I'd much rather have a nice typing keyboard than have all the LEDs light up, so I wasn't too bothered by the lighting.

The keyboard looks and feels better to type on; I definitely prefer PBT keycaps now and will look out for the keycap material in future. A side effect I wasn't expecting was that the keyboard sounds slightly different when typing on it w/ o-rings (has a deeper sound than the ABS keycaps w/ o-rings), which sounds better for me at least.

Delivery was fine, no complaints there. A bit overkill on the protective packaging though, I was expecting a smaller package, but at least I know it was protected well.

Overall, good product, decent replacement keycaps for my Ducky One.
