Birch Production Update
I'm very sorry that the birch games have not shipped yet. In our last post we highlighted a quality control issue with the production of the birch tiles. We are still working to resolve the issue but unfortunately 2015 is coming to a close and the manufacturer have shut down for the holidays. Once they start back up we will continue working toward a solution.
