The metal board is an "oil drip pan" that is sold at auto parts stores. It is quite large(25" x 36") but is movable and very sturdy. I bought mine at Auto Zone for $9.99. The metal is magnetic. After I started assembling the game I decided that I did not want to put 52 letters on magnets so I used paper clips on the blue oak tag and ran clear packing tape in between the rows. This could be made on large foam board. I did find a magnetic note pad holder that is perfect for the storage of letters. The black is duct tape that I used to make a border. I found the Boggle image on Google and used a Manila folder as a pocket. There is an imprinted logo on the metal that I wanted to hide.
This is the original game. Visit her site for the printables below:
