Sumgsn Keycaps: Affordable Custom Style for Your Keyboard

Enter Sumgsn Keycaps, a brand that’s quietly become one of my personal favorites for affordable, stylish, and surprisingly well-made keycap sets. While premium brands like GMK or Osume might grab the spotlight with their limited drops and sky-high price tags, Sumgsn offers an alternative that makes mechanical keyboard customization accessible to everyone without feeling like a compromise.

I’ve tested many of their models over the past year, and I have to admit — they’re absolutely great. The variety of designs is incredible, with color combinations that feel thoughtfully curated rather than gimmicky. One of my favorite aspects is how Sumgsn manages to deliver solid quality and extended keycap sets suitable for different keyboard sizes at a price point that makes sense.

Pros and Cons of the Cherry Profile Experience

✅ Pros:

• Ergonomic Typing Angle: Gently sloped key shape from top row to spacebar offers natural, comfortable hand positioning.
• Consistent Profile: Smoother, lower height arc compared to OEM profile; feels controlled and familiar for sculpted-profile fans.
• High-Quality Execution: Despite not being a personal favorite profile, the Sumgsn Cherry set impressed with its build quality and coherent design theme.
• Well-Thought-Out Key Selection: The included 152-key set covers extra keys like split spacebars, alternate modifiers, and novelty caps — making it easier to install even on complex layouts like the 75% Bridge75.
• Typing Feel and Sound: Delivers a clean, satisfying clack, comparable in feel and sound to premium $80+ keycap sets (e.g. Osume).
• Surprisingly Comfortable for Non-Fans: Even users typically preferring taller profiles (SA, KAT) might find this Cherry profile set surprisingly cohesive and pleasant after extended use.

❌ Cons

• Not Ideal for Fans of Taller Profiles: Users who prefer chunkier, higher-profile keycaps (like SA or KAT) may find Cherry profile less engaging or lacking in curvature.
• Trickier Key Selection for Custom Layouts: Selecting individual keys for specific layouts like 75% can be a bit more tedious due to the sculpted profile differences across rows.
• Limited Curve Depth: Compared to taller profiles, Cherry offers a subtler curve and lower key height, which may feel too flat or muted for certain enthusiasts.

Materials and Build Quality: How Durable Are They?

When it comes to mechanical keyboard keycaps, material choice is everything. It affects how your keys feel under your fingertips, how they sound when you type, how long they last, and how well they resist shine and fading over time. And here’s where Sumgsn Keycaps genuinely hold their ground against pricier competitors.

Let’s start with the material: these keycaps are made of Polybutylene Terephthalate (PBT) — widely considered the gold standard for durable keycaps. Compared to cheaper ABS plastic, PBT is tougher, less prone to developing that ugly, greasy shine after months of use, and has a more textured, satisfying feel. If you’ve ever typed on ABS keycaps and felt them get slippery over time, you’ll appreciate how Sumgsn’s PBT material stays consistent.

The legends are dye-sublimated, which is another big plus. In this process, the dye is infused into the plastic, meaning the legends won’t fade, chip, or wear off — ever. I’ve used my Autumn Osmanthus set daily for months now, and the legends look exactly the same as the day I installed them. No fading, no smudging, and no uneven print issues.

In terms of thickness, Sumgsn keycaps strike a nice balance. They’re not as thick and heavy as high-end GMK sets, but they’re far from flimsy. The walls are sturdy enough to produce a pleasant, deep sound signature when typing — not too hollow, not too plasticky. I found that paired with my Bridge75 build, they created a satisfying clack that honestly surprised me at this price point.

Fitment-wise, the keys sit securely on MX-compatible stems without wobbling, and the stems themselves are cleanly molded with minimal flashing. During my first install, every key seated properly without me having to force or shave down any stems — something I’ve had to do with a couple of other budget sets in the past.

In short: durability is one of Sumgsn’s strongest assets.
They feel built to last, stay vibrant over time, and hold their shape and texture through extended daily use — whether you’re hammering away at emails, gaming, or designing layouts late into the night.

If you’re someone like me who appreciates a good deal without sacrificing long-term value, Sumgsn’s build quality easily justifies its price tag.

Value for Money: Why Sumgsn is a Smart Buy?

In the world of mechanical keyboards, it’s easy to get swept up in the hype of premium keycap sets that can cost upwards of $100 or more. But if you’re like me — someone who loves customizing their setup without draining the bank account — Sumgsn keycaps are one of those rare, satisfying finds that deliver excellent value without cutting too many corners.

Let’s talk pricing first.
Sumgsn keycaps typically land in the $30–$45 range depending on the colorway and where you buy them. For that, you’re getting a 152 or 156-key extended set made of high-quality PBT plastic with dye-sublimated legends — features you’d usually expect in sets twice the price. It covers everything from your standard 60%, 65%, 75%, TKL, all the way up to full-size keyboards. No extra orders or partial kits necessary. That kind of versatility alone makes them worth a second look.

Now here’s where my own experience really proved the value.
I picked up the Autumn Osmanthus set initially just to experiment with some seasonal desk setups. But after installing them on my Bridge75 and typing on them for a while, I realized they felt and sounded every bit as good as my $80+ Osume sets. Great keycaps. They feel and sound every bit as good as my $80+ Osume sets, and the colors are really, really beautiful on my Bridge75 in cream. It’s rare for a budget set to hold up this well against boutique brands.

You also have to factor in the flexibility.
Having 152 keys means you can comfortably kit out multiple boards without needing to buy multiple sets. I’ve used leftover keys from my first Sumgsn set to refresh a couple of side builds, which saved me even more money.

Another overlooked benefit is the durability.
Thanks to their PBT material and dye-sublimation printing, these keycaps resist shine, wear, and legend fading over time — something cheaper ABS sets or even some low-tier PBT sets can’t promise. So not only are you paying less upfront, but you’re also getting more life out of your investment.

The only thing I wish they offered was even more print variations.
Absolutely perfect. I only wish there were even more options in this print that I could get! That’s probably the best problem a keycap brand can have — customers wanting more.

Bottom line:
If you’re looking for a keycap set that balances affordability, quality, and versatility, Sumgsn is a smart buy. Whether you’re customizing your daily driver, upgrading your gaming setup, or just experimenting with new color schemes, these keycaps give you serious bang for your buck.
