Freestanding Monitor Arm ★ For IODATA 27-inch Gaming Monitor ★ Includes Mounting Parts

This was included when I purchased the IODATA EX-LDQ271JAB 27-inch gaming monitor about six months ago.
I am selling it because I use a separate monitor arm.
It has been stored in a cardboard box without ever being opened from its bag.
As shown in the photos, there is a mark on the arm attachment part that appears to have been made at the factory.

The manufacturer's page states that it is VESA compatible.
Please understand that I do not know the detailed specifications.

All the parts that came with it are included.
The monitor is not included.

Immediate purchase is welcome.
I apologize, but I cannot accept price negotiations (_ _;)

Stand dimensions: Approximately 20 cm (depth) x 23.5 cm (width) x 1.3 cm (thickness)
Arm dimensions (excluding the monitor attachment part): Approximately 37 cm (length) x 5.7 cm (width)

- Component list: Monitor arm main unit, mounting bracket, screws, hex wrench, plastic caps
- Bracket type: Metal mounting bracket, steel screws, hex wrench
- Accessories: Plastic caps (2 pieces)

Thank you for looking.
