NIZ Electrostatic Capacitive Keyboard X99-pro White (US Layout) Wireless

I am selling this keyboard because it didn't suit me, even though I purchased it here.
The previous owner said they hardly used it. I used it for about two weeks.

Niz Keyboard X99 wireless type. The keycaps are not the rounded type.

The following is quoted from the official website:

Reduced from the full-size keyboard's 45cm, it cuts down 16% of the area, providing more space for your mouse. The extra 7cm of space can be used for your mouse or documents, improving work efficiency. It's also convenient to carry around. Because it has a layout similar to a compressed full-size keyboard, you can get used to it quickly without feeling out of place.
