Item arrived damaged in the corner.  I am working with the Wayfair vendor to resolve.  I did not have issues with wet varnish as other reviewers mentioned.  The frame is mango wood but the interior cut out is mdf.  Not bad quality. Looks more expensive than it is.  The lighter weight is a bonus in drywall.  I am hoping to repair the corner myself as it is to large of a package to easily return.  These are meant to hang vertically, BUT you could hang horizontally by adding your own picture hanging hardware.  Each panel is a different design which is nice as it adds visual contrast.  These are beautiful hanging on the wall.
