This item is used daily for work, so it shows some signs of use, but I've taken good care of it, so I think it's still in good condition. An anti-vibration sheet from Covers (2,580 yen) is already attached to the back. A co2CREA keyboard case (2,099 yen) is also included. The keyboard is not the original, but it's very user-friendly and fits perfectly. It's also durable, so you can carry your HHKB with confidence. There is no box or instruction manual, and everything in the photos is included. Connection type... Wired/Wireless (Bluetooth) Key switch... Electrostatic capacitive non-contact Keyboard layout...
