Using the Gamegenic Token Silo XL is a breeze. First, open the cover by unclipping it from the bottom. You can then place your tokens, tools, cards, and dice into the trays according to your needs. The extra - long tray is great for storing movement and range tools. When you're done using it, simply clip the cover back on all four sides for a secure closure. As for maintenance, keep it in a dry place to prevent any damage. If it gets dirty, you can use a soft, dry cloth to wipe it clean. Make sure to handle the removable trays gently to avoid any breakage. And remember, you can swap the trays with those from the original Gamegenic Token Silo and Token Silo Cards Add - on for more flexibility.
