Is this keycap set compatible with my keyboard?

Our keycaps feature standard cross-shaped stems, making them fully compatible with 99% of mechanical switches (e.g., Cherry, Gateron, Kailh, and all PIIFOX switches). Note: Not compatible with Topre or low-profile switches.

Does this set fit custom layouts like 75% or 65% keyboards?

Perfectly fits! It supports most standard and custom ANSI layouts, including 60%, 65%, 75%, TKL (80%), and Full-size (100%).

What material are the keycaps? Will they get shiny over time?

We use premium, high-content PBT material, which is harder and drier than standard ABS, making it highly resistant to developing a greasy "shine" over time. It features a finely textured surface for a comfortable typing feel.

Will the beautiful artwork and legends fade or wear off?

We utilize an advanced 5-sided dye-sublimation process. The ink is deeply embedded into the PBT plastic at high temperatures, ensuring the vibrant artwork and legends will never fade or wear off, no matter how intensely you type.

Will there be any color difference between the actual product and the pictures?

We strive to render our product photos as true to life as possible. However, due to variations in monitor calibrations, lighting conditions, and the dye-sublimation process, actual colors may vary slightly from what you see on screen.

How should I clean them without damaging the artwork?

Because the artwork is sublimated into the plastic, you can safely wash them. Simply remove the keycaps, soak them in warm soapy water, scrub gently with a soft brush, and let them air dry completely before reinstalling.

PMTD

PMTD takes its name from the initials of Plus, Minus, Times, and Divide — the four fundamental operations of arithmetic. With a single set of keycaps, we set out to turn math's most basic operations into a language your fingertips touch every single day. Addition, subtraction, multiplication, and division are the first operations humankind ever learned — so simple they're almost overlooked, yet they underpin every complex calculation in the world. A keyboard is no different. Built from nothing but the humblest square blocks, it can write code, shape words, and keep the entire digital world running. What PMTD seeks to express is exactly this power of building complexity from simplicity — the most elemental pieces, combined into infinite possibility.

PBT KEYCAPS

Our keycaps are crafted using advanced 5-sided dye-sublimation technology, delivering vivid, full-color printing across every surface. Made from durable PBT material, these keycaps feature legends that are resistant to fading, even with long-term use.

DESIGN INSPIRATION

The inspiration came by chance. As we were staring blankly at a keyboard one day, it suddenly hit us — a keyboard and mathematics are really the same thing.In the world of math, even the most massive formula breaks back down into addition, subtraction, multiplication, and division. In the world of keyboards, even the most complex program is typed out from individual square keycaps, one at a time. Both obey the same humble truth: the simplest units make up the most complex systems. Once that thought surfaced, it never let go — and PMTD was born.
