CSA Blueberry Keycap Set | Uniform CSA Profile PBT Keycaps

Generic keycaps in generic colorways. The UreLab CSA Blueberry Keycap Set is something more intentional — a deep, rich blueberry purple that looks hand-picked rather than mass-produced, in the underrated CSA profile that gives flat-typists and minimalists exactly what they’ve been looking for.

CSA Profile – Flat, Uniform, and Underrated

• Uniform row height — every key sits at the same level for a clean, consistent typing surface
• Spherical top with a gentle concave dish — guides your fingertips naturally without aggressive sculpting
• Ideal for those who switch between rows frequently (programmers, gamers, custom layout users)
• A refreshing alternative to Cherry or OEM for typists who prefer a flatter, modern feel

Blueberry Colorway – Deep & Deliberate

• Rich blueberry purple tones — not pastel, not neon, just the right depth
• Pairs beautifully with silver, black, or white keyboard builds
• Subtle enough for professional environments, distinctive enough to stand out

Premium PBT Build

• High-density PBT material — shine-proof, fade-proof, wear-proof
• Legends stay crisp and legible after years of daily use
• Solid, satisfying feel on every keystroke

Compatibility

• MX-switch compatible — fits standard ANSI layouts from 60% to 100%
• 60–62 key (60%) / 82–84 key (75%) / 87 key (TKL) / 96–98 key / 104–108 key (Full-size)

Frequently Asked Questions

Q: What is CSA profile and how does it compare to Cherry profile?
A: CSA is a uniform profile — all rows are the same height. Cherry profile is sculpted, meaning each row has a different angle. CSA gives a flatter, more modern typing feel that many programmers and custom layout users prefer.

Q: Are these compatible with hot-swap keyboards?
A: Yes. The CSA Blueberry keycap set fits all standard MX-stem switches, including hot-swap PCBs.

Q: Do the legends fade over time?
A: No. The legends are produced using a process that bonds them into the PBT material — they will not fade, peel, or wear off under normal use.
