AI Verdict
This is a 20-piece set of 1U R4 PBT blank keycaps for MX switches, designed for keyboard customization.
This set is a situational fit because it provides durable PBT blank keycaps for MX switches, which is great for specific customization or touch-typing practice. However, the limited 20-piece count and uniform R4 profile restrict its use as a complete replacement set for most keyboards.
If you need a full set of blank PBT keycaps with sculpted profiles for different rows, look for sets explicitly stating 'full set' or '104/87/61 keys' and specifying multiple row profiles (e.g., R1-R4).

Pros
- Constructed from Polybutylene Terephthalate (PBT) material, which offers high mechanical properties and resistance to aging.
- The PBT material is known for its durability and resistance to developing a shiny surface over time, unlike ABS keycaps.
- The blank design allows for a minimalist aesthetic and can aid in touch-typing practice.
- Includes 20 keycaps in a mixed rainbow color assortment, providing options for visual customization.
- Compatible with a wide range of MX-style switches, including Cherry MX, Gateron MX, and Kailh MX.
Cons
- The set only contains 20 keycaps, which is insufficient for a full keyboard layout.
- All keycaps are 1U R4 profile, limiting their use to specific rows or as accent keys.
- Absence of legends means users must rely on muscle memory or external references for key functions.
- The mixed color assortment might not suit all aesthetic preferences, as specific color quantities are fixed (e.g., 2 black, 2 white, etc.).
- The included keycap puller is a basic wire type, which some users might find less comfortable than more ergonomic designs.
Dimension Scores
The PBT material offers a slightly textured feel compared to smoother ABS, which some users prefer for typing.
The PBT material provides a snug fit on MX stems, ensuring the keycaps remain stable during use.
As blank keycaps, they do not allow backlighting to shine through, making them unsuitable for illuminated legends.
Made from PBT, these keycaps are described as strong and durable, offering high mechanical properties and resistance to high temperatures and aging.
Best For
- Adding color accents to a mechanical keyboard with MX switches.
- Users practicing touch-typing who prefer a blank keyboard surface.
- Custom keyboard builds where specific 1U R4 blank PBT keys are needed.
- Programmers and gamers who want to personalize specific key positions without legends.
Not Recommended For
- Replacing all keycaps on a standard full-size or TKL keyboard.
- Users who rely on key legends for typing or navigation.
- Keyboards with non-MX style switches.
- Anyone needing a uniform profile across multiple rows, as these are all R4.
Watch Out For
- The 20-piece count means you'll need multiple sets or other keycaps to cover a full board, which isn't clear from just seeing 'keycaps' in the title.
- Since all keycaps are R4 profile, they won't provide the sculpted feel of a full OEM profile set across different rows, which can feel inconsistent if mixed with other profiles.
- The blank nature means no backlighting shine-through, so if your keyboard has RGB, these won't show the light through the legends.
- The mixed color pack might result in unused colors if you're aiming for a specific two-tone or monochromatic look.

What Buyers Say
Users generally find PBT keycaps to be durable and resistant to shine, which is a common issue with ABS keycaps. The blank design is often chosen for aesthetic reasons or to encourage touch-typing. The set's 20-piece count and uniform R4 profile mean it's primarily for accenting or specific key replacements rather than a full board. The mixed rainbow colors offer customization, but the fixed quantities of each color might not always align with a user's exact needs.
“Look, if you just need some extra PBT blanks for your F-row or to make a few keys pop with color, these are fine. But don't think you're getting a whole set, cause you're not, and they're all the same height, which is kinda weird if you mix them.”
Common Praise
- The PBT material feels durable and doesn't get shiny after extended use.
- The blank design provides a clean, minimalist look.
- The mixed colors allow for creative customization and adding visual flair.
- They fit snugly on MX-style switches.
- Includes a basic keycap puller, which is convenient.
Common Complaints
- Only 20 keycaps are included, not enough for a full keyboard.
- All keycaps are R4 profile, limiting their placement for a sculpted feel across rows.
- No legends mean it's not suitable for users who need visual cues for typing.
- The specific color distribution (2 of each color) might lead to unused keycaps if only certain colors are desired.
Ownership Tips
- The PBT material holds up well to daily finger oils, maintaining its matte texture.
- The colors are consistent across the 20 pieces in the set.
- The R4 profile feels natural for the top row or as uniform accent keys, but can feel out of place if used on lower rows with other sculpted keycaps.
- The blank nature truly forces you to rely on touch-typing, which can be a learning curve for some.
Frequently Asked Questions
Are these keycaps compatible with all mechanical keyboards?
These keycaps are compatible with mechanical keyboards that use MX-style switches, such as Cherry MX, Gateron MX, and Kailh MX. They will not fit keyboards with non-MX switches.
Do these keycaps have any legends or symbols?
No, these are blank keycaps, meaning they have no printed legends or symbols on their surface. This is ideal for a clean look or for touch-typists.
What does '1U R4' mean?
1U refers to the standard single-key width. R4 indicates the row profile, typically used for the top row (Esc, F-keys) on an OEM profile keyboard. All 20 keycaps in this set share this R4 profile.
Will these keycaps shine over time?
These keycaps are made of PBT material, which is known for its resistance to developing a shiny, greasy look over extended use, unlike ABS keycaps.
Can I use these for a full keyboard?
No, this set only contains 20 keycaps. It's designed for accent keys or specific sections of a keyboard, not for a complete replacement of all keys.
Buying Guide
When you're looking at keycaps, especially blank ones, you need to think about what you actually want them for. Are you just trying to add a splash of color to a few keys, or do you want to replace every single key on your board? This set is for the former. Also, consider the material: PBT is generally tougher and won't get that greasy shine over time like cheaper ABS keycaps can. Finally, the 'profile' and 'row' matter a lot for how comfortable they feel under your fingers.
Material: Polybutylene Terephthalate (PBT)
PBT is a type of plastic known for its durability and resistance to wear. Unlike ABS plastic, PBT keycaps are less likely to develop a shiny, smooth surface from finger oils over time, keeping their textured feel longer. Think of it like a durable, matte finish versus a glossy one that shows fingerprints easily.
Profile: OEM R4 Profile
Keycap 'profile' refers to its shape and height. OEM is a common, sculpted profile where different rows have different heights and angles. R4 specifically refers to the profile of the top row (like the Esc key or F-keys). Since all 20 keycaps in this set are R4, they'll have a uniform height and angle, which is great for accent keys but might feel odd if you try to use them on other rows of a sculpted keyboard.
Number of Keys: 20 Keys (1U)
This tells you exactly how many keycaps you're getting. '1U' means each keycap is the standard size of a single letter key. With only 20 keys, this set isn't meant to cover an entire keyboard. It's more for customizing specific keys, like your Esc key, arrow keys, or a few function keys, to add color or a blank aesthetic.
Alternatives
If this set isn't enough, look for 'full set PBT keycaps' with 'Cherry profile' or 'OEM profile' that specify a higher key count (e.g., 104, 87, or 61 keys) and include different row profiles for a more ergonomic typing experience.
