HHKB Professional HG

PD-KB500J

Happy Hacking Professional HG PD-KB500J

Released for the 10th anniversary of the original Happy Hacking Keyboard.

This model features an aluminum case with greater height adjustability and included laser engraving to order.

An even rarer variant, the HHKB Professional HG Japan edition includes traditional wajima-lacquered and gold-dusted keycaps.

Happy Hacking Professional HGs are by far the rarest and most valuable Happy Hacking models ever produced. Their appearance on the secondhand market is virtually nonexistent.
