Thank you for considering this product. This is a dual monitor arm from ELECOM. I am selling it because I no longer need it. The main unit and hex wrench are included. There are no major scratches or scuffs, but it has been used for about two years, so I have classified it as having some minor scratches and dirt. Please understand that this is a used item and has been stored by an individual. It will be shipped via anonymous delivery using Rakuraku Mercari. ○ Product Overview Movement Type: Swivel, Tilt, Rotate Brand: ELECOM Maximum Compatible Size: 27 inches Minimum Compatible Size: 13 inches Compatible Devices: Monitor Maximum Tilt Angle: 45 degrees Manufacturer: ELECOM ○ About this product This is a liquid crystal display arm compatible with liquid crystal displays from 13 inches to 27 inches.
