Using the Gamegenic Token Silo XL is a breeze. First, open the cover by unclipping it from the sides. You can use the extra - long tray to store movement or range tools. Then, place your tokens, cards, dice and other items in the appropriate trays according to their size. You can mix and match trays from the original Token Silo and the Cards Add - on to customize the storage. When you're done using it, clip the cover back on all four sides for a secure fit. If you want more space on the gaming table, clip the cover to the bottom. As for maintenance, just use a dry cloth to wipe the inside and outside of the silo regularly. Avoid using harsh chemicals as they may damage the plastic. Keep it in a cool and dry place to prevent any warping or deformation.
