Here's the English translation of the text:

Keychron K5 Pro, a full-size, low-profile mechanical keyboard with QMK/VIA support.

Compatible with both Mac and Windows.

- Model Name: Keychron K5 Pro
- Model Number: K5P-A1
- Type: Full-size mechanical keyboard
- Color: Black
- White Backlight
- Red Switches
- Accessories: Type-A to Type-C cable, keycap puller, Windows-compatible keycaps, 2 switches, switch puller

Purchased directly from an overseas website and shipped by air, so the outer box has dents and scratches.

Also, due to the above, it does not have the technical conformity mark (Japan's Radio Law). The original cable (unused) for wired use is included.

【Scratches/Stains】
Used for about 1 year for work. There is a feeling of use and shine.

【Reason for being "as-is"】
As far as I know, the U, I, and O keys have poor responsiveness.
I tend to type with a tough touch, so I haven't had much trouble using it, but those with a lighter touch may find the keys less responsive. There may also be other keys that are less responsive.

Please consider this as an "as-is" item and understand the condition before purchasing.
