Thank you for viewing from among many products. This is a PFU keyboard HHKB Professional HYBRID Type-S, Japanese layout / Sumi (black). The keyboard本体, box, instruction manual, and proof of delivery are included. (Batteries and other items besides the main unit are not included) Optimal for high-speed input, it features a non-chattering electrostatic capacitive key switch, ideal key touch and long life that doesn't tire even after long hours of use, Bluetooth and USB connection (Type-C), key map change function, and the "Type-S" key structure excels in Speed (high-speed typing) and Silent (quietness). Furthermore, it's a keyboard equipped with all desirable functions, such as a rational key layout and three-stage tilt adjustment. The "electrostatic capacitive non-contact method" switches without contact (without bottoming out), realizing a deep stroke and exquisite key touch. The supple and comfortable touch adds value to typing with joy. The "HYBRID Type-S" also adopts a key structure that excels in high-speed typing (Speed) and quietness (Silent). "HYBRID Type-S" and "HYBRID" support Bluetooth and USB connections. You can freely switch between wireless and wired, so it doesn't matter which device you use. With Bluetooth, by registering devices in advance (up to 4), you can connect to the desired device immediately with simple key operations. The USB uses a Type-C connector that can be "reversed," significantly reducing stress during connection.
