This is the PFU high-end keyboard "HHKB Professional HYBRID". It's the popular "Sumi (Charcoal Black)" color, English layout (US layout) model. ■ Condition: Purchased about 3 months ago, but I haven't had much opportunity to use it, so I'm selling it. It's been used only a few times, so there's no shine or dirt on the keycaps, and it's in very clean condition, almost like new. Of course, it works perfectly. ■ Product Details: Model: Professional HYBRID Model Number: PD-KB800B Color: Sumi (Black) Layout: English layout (US) Connection: Bluetooth (wireless) / USB Type-C (wired) ■ Accessories: Original box, instruction manual, batteries (everything that came with it at the time of purchase) ■ Features: ・Electrostatic capacitive non-contact method: The ultimate typing feel unique to HHKB, "scosco" (a light, satisfying sound). ・Hybrid connection: Supports both Bluetooth and USB connections. I think this is a great deal for those considering buying a new one. It will be disinfected and cleaned before shipping. #HHKB #PFU #HappyHackingKeyboard #keyboard #EnglishLayout #USLayout #ElectrostaticCapacitiveNonContactMethod #Bluetooth #Wireless
