Dual black monitor arm with adjustable angles. - Color: Black - Adjustment: Angle adjustable - Material: Metal The brand name is not written anywhere, so it is currently unknown, but it resembles products from Ergotron and StarTech. It's a vague memory, but it was over 20,000 yen when new. It's heavy and sturdy. It has a robust construction with two clamps on the side that attaches to the desk, etc. There are some minor scratches that are not easily noticeable, but there are no problems with use. There are no instructions. This is a used item, so please understand that. I used it with the Philips 27-inch display I was selling. It is also possible to remove one arm and use only one. It's convenient because you can smoothly set the display at your desired angle and position without taking up space on the edge of a desk or shelf. The measuring tape in the photo is not included. Thank you for looking.
