Purple Yellow Green Gradient PBT Double Shot 133-Key Side-lit Keycap

In this review of the Purple Yellow Green Gradient PBT Double Shot 104 133 Keys Side-lit keycaps, the bottom line is simple: this set is for custom keyboard users who want a bold gradient and reliable shine-through legends for south-side LED layouts. The reviewer found the PBT double-shot construction and slightly taller OEM profile deliver durable, textured keys and strong legend clarity when used on compatible keyboards. This set includes keycaps only, so buyers should already have a compatible MX-style mechanical keyboard and be aware of spacebar sizing limits.

Key Features

• PBT double-shot construction: Provides durable, wear-resistant key surfaces with legends molded for long-term shine-through performance.
• Side-lit shine through: Designed to let south-side LEDs illuminate legends clearly, enhancing backlit effects on supported boards.
• OEM profile: Slightly taller than Cherry profile, offering a familiar sculpted feel for users who prefer a taller keycap shape.
• 133-key coverage: The 133-key option supplies extra keys beyond a 104 ANSI set for extended layouts and replacements.
• Compatibility with MX switches: Fits Cherry MX, Gateron MX, Kailh MX and most other MX-bottomed keyboards with standard spacebar sizing.

Who It's For

This keyset is best for mechanical keyboard hobbyists who use boards with south-side LEDs and standard MX switch stems. It suits anyone who wants a vivid purple-to-green gradient and durable PBT keycaps that hold up to heavy typing while showing backlight through the legends.

Users who should look elsewhere include those with north-side LED PCBs seeking dramatic underglow effects and anyone whose keyboard uses nonstandard spacebar sizes such as 6u, 6.5u or 7u without ordering extra keys. Also note the package contains keycaps only, not a keyboard.

Pros & Cons

Pros

• Strong, wear-resistant PBT double-shot legends keep legends readable and resist shine from oils.
• Well suited to south-side LED setups, producing clear backlit legend illumination.
• OEM profile gives a comfortable, slightly taller feel compared with Cherry profile alternatives.
• Includes extra keys in the 133-key kit to cover more layouts and replacements.

Cons

• Backlight performance is noticeably weaker on north-side LED keyboards, limiting lighting effects for some builds.
• Not compatible with keyboards that use 6u, 6.5u or 7u spacebars without additional keys.

Specifications

Our Verdict

For south-side LED mechanical keyboards with MX stems, this purple-yellow-green gradient PBT double-shot set is a practical, visually striking upgrade that pairs durability with clear shine-through legends. It offers good value for builders who need a full 133-key kit and prefer the slightly taller OEM feel, but buyers must confirm their spacebar size and LED placement before ordering.
