I've been staring at gmk modern material on my desk for about a week now, and I think I've finally figured out why it's so hard to take off my board. It isn't just another grey keycap set in a hobby that is already drowning in shades of slate and charcoal. There's something about the specific way these colors interact with the light that makes my entire workspace feel a lot more "adult" and a lot less like a neon-soaked gaming den.
If you've been hanging around the mechanical keyboard scene for a while, you know the name Biip. He's the designer behind some of the most iconic sets ever made—think GMK Dots or Milkshake. But while those sets are loud, playful, and full of personality, this one feels like he decided to go back to basics and master the fundamentals of industrial design.
The Beauty of Industrial Minimalism
Most of the time, when a designer says a set is "minimalist," it's usually just a polite way of saying it's boring. You get a light grey and a dark grey, and that's about it. But with gmk modern material, the nuance is in the texture and the subtle shifts in tone.
The set is actually split into two primary colorways: "Concrete" and "Stone." Concrete is that crisp, light-leaning grey that looks like it belongs in a high-end architectural firm. Stone is deeper, moodier, and leans into those brutalist vibes that are so popular in custom keyboard circles right now. What I love most is that it doesn't try too hard. It's the kind of set that lets the keyboard itself do the talking, especially if you're rocking a high-end aluminum case.
Why the Legends Matter So Much
I've always been a sucker for custom icons. Standard GMK legends are great—they're classic, readable, and consistent—but Biip has a way of redesigning the modifier icons that just feels right. Instead of the word "Shift" or a standard arrow, you get these clean, geometric shapes that fit the "material" theme perfectly.
The legends on gmk modern material are super crisp, which is what you expect from GMK's double-shot ABS process. Since the legend is literally a separate piece of plastic molded into the cap, you never have to worry about the letters fading. But more importantly, the contrast is dialed in perfectly. On the Stone kit, the lighter legends pop just enough to be readable without looking harsh. It's that balance that makes the set look so expensive once it's actually mounted on a board.
Concrete vs. Stone: Which One Wins?
It's a tough choice, honestly. When I first saw the renders for gmk modern material, I was leaning heavily toward Concrete. It has this very clean, Apple-esque aesthetic that looks incredible on silver or white boards. It feels airy and fresh.
But then I saw Stone on a dark forest green board, and my mind completely changed. Stone has this gravity to it. If you have a black, navy, or even a raw aluminum board, Stone gives it this heavy, industrial look that is just chef's kiss. Most people end up buying both just so they can mix and match the accent keys, which is a dangerous game for your wallet, but hey, that's the hobby for you.
The Typing Experience (and the Shine)
We have to talk about the elephant in the room: ABS plastic. Some people act like ABS is a dealbreaker because it eventually "shines." If you type on these for a few months, the matte texture is going to wear down, and they'll start to look a bit glossy.
But here's my hot take: I actually like the shine on a set like gmk modern material. There's something about a well-loved, shiny GMK set that looks like a vintage tool. It shows that the board is actually being used, not just sitting on a shelf for Instagram photos. Plus, the sound of GMK's thick ABS is still the gold standard. It has that deep, poppy "thock" that PBT sets struggle to replicate. When I'm hammering away at an email, the acoustics of these caps on a well-lubed linear switch is basically therapy.
How to Pair This Set With Your Board
The best part about gmk modern material is its versatility. You don't have to overthink it.
- Silver Aluminum: Go with Concrete for a seamless, monochromatic look.
- Black or E-White: Stone creates a high-contrast, professional vibe that looks great in an office setting.
- Polycarbonate: Either one works, but the way the internal RGB (if you're into that) reflects off the bottom of these grey caps is surprisingly cool.
I currently have mine on a silver 65% board with a brass plate, and the way the grey plastic plays against the metallic sheen of the case is just perfect. It's understated. It doesn't scream "I spent way too much money on a keyboard," even though we both know I did.
The Struggle of the Group Buy
If you're new here, you might be wondering where to actually buy gmk modern material. That's the tricky part. Like most high-end keycap sets, this started as a group buy, which means people paid for it a year (or more) before it actually landed on their doorsteps.
If you missed the initial run, you're looking at the aftermarket or hoping for "extras" from vendors. It's a bit of a headache, I won't lie. You'll see people on forums and Discord servers hunting for these kits like they're gold. Is it worth the markup? Well, considering how many "budget" sets try to copy this look and fail to get the colors quite right, I'd say yes. There's a certain depth to the grey that the cheaper clones just can't catch.
Is It Too Boring?
I've heard some people say that gmk modern material is a "safe" set. And you know what? They're right. It is safe. It's not a crazy colorway with neon pink accents or weird sub-legends. But "safe" is exactly what I want when I'm actually trying to get work done.
When you have a keyboard that looks like a rainbow, it can be a bit distracting. But a grey-on-grey setup? It's calming. It feels like a piece of hardware rather than a toy. It's the "Modern" in the name—it's designed for contemporary spaces where you want things to look sleek and integrated.
Final Thoughts on the Set
At the end of the day, gmk modern material is a testament to the idea that you don't need a million colors to make something beautiful. Biip took the most basic elements—stone and concrete—and turned them into a tactile experience that just feels premium.
If you're tired of the constant cycle of "hype" sets that look cool in photos but clash with your room, this might be the one. It's an endgame-tier set that doesn't demand your attention, but it definitely rewards it once you start typing. It's refined, it's durable (in its own way), and it makes every board it touches look ten times better. Just be prepared to fall down the rabbit hole of trying to find the "perfect" grey board to match it. Don't say I didn't warn you.
