Stand-Up Desk Converter

We are selling this new, barely-used stand-up desk converter that can be placed on top of a desk for a fully functioning stand-up desk setup. We ended up not needing it and didn't use it.

Please see the attached photos and the link to the original item here (Teak color):

Thanks!
