135 PCS Custom PBT Keycaps Review: Is This Side-Print Set Right for Your Mechanical Keyboard?

This 135-key black PBT keycap set adds side-printed shine-through styling and Cherry profile shaping for $39.84. It suits a compatible mechanical keyboard refresh, but it is not a complete keyboard.

Last updated Aug 24, 2026

Shopping for mechanical keyboards is not always about replacing the whole board. If your current setup works well but looks plain, a keycap swap can change its appearance-provided the set matches your switches and layout. The 135 PCS Custom PBT Keycaps set focuses on a black, technology-themed look with side-printed legends and shine-through styling.

Quick verdict

At $39.84, this is a focused choice for someone who wants to customize the look of a compatible mechanical keyboard rather than buy a new typing device. Its main appeal is the combination of black PBT caps, a 135-key count, Cherry profile shaping, and side printing designed to let keyboard lighting show through the legends.

The important trade-off is straightforward: this is a keycap set, not a complete mechanical keyboard. The stated fit is for Cherry MX switches, so the switch type on your existing board matters before you choose it.

Who it suits

This set makes the most sense for a shopper who already owns a compatible mechanical keyboard and wants a visible style change. The "Cool Tech Style" theme, black color, and side-printed legends give the upgrade a specific visual direction instead of a plain replacement look.

It is also a practical match for buyers who want shine-through lettering. The description notes that the side-printed design allows keyboard light to shine through the fonts, with LEDs working best when facing south. That detail is useful for anyone choosing keycaps partly around backlighting.

What stands out

The material and finish are central to the appeal. These are described as PBT keycaps with an oil-resistant coating intended to resist fingerprints, sweat, and oil. Dye sublimation is also specified, with the description positioning it for long-term resistance to fading.

The 135-key format gives the set a broad-looking replacement package, while the Cherry profile keeps the design tied to a familiar keycap shape. The result is a customization purchase with a clear aesthetic purpose: black caps, side legends, and a technology-inspired theme.

Meaningful trade-offs

The biggest limitation is compatibility scope. Although the set is described for Cherry MX switches and mechanical keyboards, that wording does not make it a universal fit for every keyboard or switch design. A buyer with a non-Cherry-style switch should treat the stated compatibility as a constraint, not a guarantee of a match.

There is also a style trade-off. Side-printed legends are distinctive, but shoppers who prefer conventional top-printed lettering may find the layout less aligned with their taste. The set's usefulness depends on wanting that specific visual treatment.

Bottom line

The 135 PCS Custom PBT Keycaps set is a sensible pick for a compatible Cherry MX mechanical keyboard when the goal is a black, side-printed, shine-through makeover. At $39.84, it delivers a defined customization concept rather than a full keyboard upgrade. Choose it for the PBT finish, 135-key format, and technology-themed lighting look; skip it when you need a complete keyboard or do not use a compatible switch style.
