Using this dice tower is super easy. First, open the lid of the dice tower. Drop your dice through the injection - molded ramps on top. The ramps will make sure the dice roll randomly. The lid can be flipped down, and the dice will fall into the walled catching tray. When you're done playing, simply flip up the attached tray. You can store more than 40 standard - sized RPG dice in it. Then, use the strong magnetic closure to keep the dice tower shut. As for maintenance, keep it away from sharp objects to avoid scratching the leatherette exterior. Also, don't expose it to extreme heat or moisture. This will help your dice tower last a long time.
