Harmonizing your thoughts has never looked so good. Harmony whiteboards are a versatile and gorgeous way to brainstorm. Taking today's latest color trends and interior fashions into consideration, we've created the perfect palette of dry-erase boards to choose from. The unframed, tempered, colored glass is ¼” thick, has flat polished square edges, and a frosted backing. The non-porous surface will not ghost or stain and works with standard dry erase markers. Pre-drilled mounting holes are inset into the glass and 1” diameter satin aluminum standoff hangers create a 1¼” spacing between the wall and glass. The whiteboard features a clear acrylic rear-mounted accessory holder, complete with markers and eraser. For easy marker visibility, it is best to mount on light to medium colored walls. It is backed with a 50 year warranty, made in the USA, and is TAA compliant.
