sought-after ! 【JustSystems Topre】Realforce 108UBK-JS (ZH0100)

I am selling a Topre 108-key Japanese layout USB keyboard as part of a collection clear-out. As the product name indicates, this is a collaboration model with JustSystems (-JS, ZH0100).
My environment is pet-no-cost and smoke-free. The configuration includes the main unit and the original box; the instruction manual is not included.

【Declaration for Sale】
・The condition of the exterior, keycaps, plate, etc., is as follows, based on the seller's subjective assessment:
Case Exterior: 3/5 (assorted shine and repair around the arrow keys)
Keycaps: 3.5/5 (no noticeable damage or print wear)
Plate: 4/5 (no noticeable damage or rust)
・complete keys and LEDs have been tested and confirmed to be working (Windows 11 / connected to a USB 3.0 port via an extension cable)
・Keycaps and case have been cleaned with electrolytic water non-woven fabric.
・Overall cleaning with a Dyson brush vacuum cleaner.
・The original box has damage commensurate with its age.

The cleaning of the unit, both inside and out, has been thorough, so you should not feel any discomfort upon receiving it.
However, as this is a product from over 10 years ago, please understand that it is sold as-is, with no returns or exchanges. Please refrain from purchasing if you are looking for a fancy-latest condition or a complete product without any missing parts, or if you are new to vintage keyboards.
Also, as the first-generation Realforce was produced before the advent of the USB 3.0 standard, it may not be recognized in Windows 10 or later / USB 3.0 environments. It may work by using a USB hub or extension cable, but this issue is exempt from liability, so please consider purchasing only if you understand this.

As this is a product that will be handled, I will thoroughly clean it with baking soda electrolytic water non-woven fabric and dust it. After the final operational check, I will pack the original box with air caps for shipment.
