Because we can't stand to throw out perfectly good stuff, we try to reuse and recycle everything we can. That's where this new product came from. These Eleven Little Black Squares (ELBS) were cut out of black Plexiglas to make the holes in our Volcano Boards... so they fit perfectly back in again. They were so cool we couldn't stand pitching them, so we saved them and are now offering them to you. What can you do with eleven little black squares you ask? You need eleven of them to convert a 6x6 MegaVolcano board into a regular 5x5. Or just get some to play with: block off certain spots, or even make a custom shaped board!
