PBT Keycaps 150 Keys Purple FOA Profile Keycap Set - Durable

In this review of the PBT Keycaps 150 Keys Purple FOA Profile set the bottom line is simple: it is a compact, durable upgrade for anyone who wants a consistent purple look plus long-lasting legends. The set is aimed at mechanical keyboard users who value build quality and a clear, fade-resistant print; the dye-sublimation process and PBT material are the single biggest reasons to buy, since they deliver a matte, anti-grease finish and legends that penetrate the plastic rather than sit on top. This reviewer found the set especially well suited to smaller layouts and custom Alice or split-space configurations.

Key Features

• PBT material: Thick, matte PBT resists shine and feels firmer than ABS, which keeps keys looking newer for longer.
• Dye-sublimation printing: Legends and patterns are embedded into the keycap material, producing crisp, durable legends that do not rub off easily.
• FOA profile: The stepped FOA profile helps fingers land predictably row to row, improving comfort during extended typing sessions.
• 150-key set: A full set with extra keys and a 7U/split spacebar option supports compact layouts like 61/64/68 and Alice-style keyboards.
• Wide compatibility: Cherry MX and other cross-stem mechanical switches are supported, making this set usable across most custom builds.
• Sturdy packaging: The included PBT tray with cover and thick outer box protects keycaps in transit and storage.

Who It's For

The set is ideal for hobbyists and typists who want a cohesive purple theme on compact or custom keyboards such as 61, 64, 68, 75, 84, 87, 96, 98, 104 or 108 layouts, and for people who prefer a durable, matte finish that resists finger oil. It also suits builders who need extra keys like a 7U or split spacebar for Alice and split-space configurations.

Less suitable are users who require non-standard stem mounts, unusual keycap profiles other than FOA, or those who want translucent or backlit legends-dye-sublimation on PBT delivers opaque, permanent legends but does not support light transmission.

Pros & Cons

Pros

• Durable PBT material with anti-grease coating keeps keycaps looking clean under heavy use.
• Dye-sublimation ensures crisp, long-lasting legends that resist wear and fading.
• FOA stepped profile improves typing comfort and finger placement ergonomics.
• Includes extra keys and 7U/split spacebar options for versatile layout support.

Cons

• Not suitable for backlit keyboards because dye-sublimation on opaque PBT does not allow legend illumination.
• FOA profile may not match every user's preferred keycap shape if they are accustomed to SA, OEM or Cherry profiles.

Frequently Asked Questions

Will these keycaps fit Cherry MX switches?
Yes. The set is compatible with Cherry MX and other switches that use the standard + cross-stem mount.

Are the legends prone to fading?
No. Dye-sublimation embeds the legend into the PBT material so prints are durable and resistant to rubbing and wear.

Can these be used on backlit keyboards?
They are opaque PBT with dye-sublimated legends, so they will not transmit backlight and are not intended for illuminated keycap use.
