Apply the peel and stick base bottoms. Peel and stick each base with a base bottom. The base bottoms are part of the LITKO base and tray system, allowing you to use flex magnet, and flex-steel together to hold your figures firmly in place, and avoid knocking your figures over the gaming table.
When planning your purchase for base bottoms and tray inserts, be aware that we highly recommend using the magnet in combination with the flex-steel. These two different materials will give you the strongest magnet bond between the two parts. Magnet on magnet suffers from a polarity issue if they are not aligned with one another properly, and will not be attracted to each other, but repelled, making it more likely to have a figure drop.
