These lovely blackboards are framed by hand in beautiful 6cm wide & 2.5cm deep old white wood, using traditional framing methods. The board itself is made from galvanised steel so highly magnetic & then given 5 coats of best quality blackboard paint. Great products should be both stylish & practical & this certainly fits that brief. A great addition to any kitchen, office or hallway etc. Can be hung landscape or portrait (comes with fixings). The grain of the wood will obviously vary, but the colour will be consistent as shown because the same varnish is used on all frames. Not suitable for liquid chalk/marker pens...just chalk!
