Where can I buy the blackboards they have in the kitchens at Center Parcs?

I went to Center Parcs recently and we had a large frameless blackboard or chalkboard in our kitchen. We want to get one made to measure for our kitchen but can't seem to find the ones we had at Center Parcs. They are sturdy and frameless and have a small lip at the bottom for your chalks. Does anyone know where I can buy these chalkboards? Thanks
