HHKB Professional Hybrid Type S US version, black, beautiful condition. I bought this in 2022, but I couldn't get used to the layout, so I bought the JIS version, and I've been storing the US version in its case. There are no accessories, only what is pictured. The actual usage period is about 2 months. It's in beautiful condition, but please refrain from purchasing if you are concerned as it is a used item.
