Hi there, this a VonHaus Dual Monitor Stand for 13-27" Screens. Below is the blurb from Amazon when I bought it.
This is unused as I found another solution with my new monitors.
It would need to be picked up from Hammersmith Grove, W6.
Thank you for looking and please don’t hesitate to get in touch for any additional information.
