Overview

The PFU HHKB Professional Series Keycap Set PD-KB420KTLPN is the fourth release in the HHKB Color Keycap Project, featuring a wisteria-inspired soft purple hue. Designed for Japanese-layout HHKB Professional keyboards, these keycaps are blank (no legends), letting the color speak for itself. The set includes 69 keycaps and a keycap puller. It’s an easy way to personalize your typing experience without buying a whole new keyboard. The wisteria color adds an elegant, calming accent to your desk setup. You can swap all keycaps for a full transformation, or mix-and-match with previous HHKB color sets like Sakura, Wasabi, or Tanpopo to create your own unique palette.

It does NOT support the HHKB Studio series. Installation requires the included keycap puller and careful handling—refer to the manual to avoid scratches. All modifications are done at your own risk.

Best Use Cases

  • Ideal for daily HHKB Professional users who want to refresh their keyboard’s look. The blank caps appeal to touch typists who don’t rely on legends, but beginners who need label references should avoid this set. - Great for collectors of HHKB color keycaps. If you already own Sakura, Wasabi, or Tanpopo sets, adding Wisteria expands your customization options. - Perfect for those who appreciate a muted, elegant purple aesthetic on their desk. The blank design keeps the focus on the color. Studio series owners should look elsewhere, as this set isn’t compatible.
