Tournament Bracket Dry Erase Magnets are a great way to track the big tournament be it the big national one or the local one. The 2x3 magnet has space for up to 64 teams but is easily used for smaller brackets with fewer teams. The printed magnet will stick securely to any magnetic whiteboard or other steel surface. This high quality magnet will stick to any magnetic receptive surface. The dry erase surface works great with dry erase or damp erase markers and is sure to last for many years of tournaments. Tip: It is not recommended to clean these boards with anything containing ammonia which is found in most glass cleaners.
