Using the Game Shell is easy. First, you can customize the interior compartments according to your needs by adjusting the two removable dividers. Place your double - sleeved cards, tokens, dice, or small games inside. For travel, you can use the adjustable shoulder strap or carry it by the reinforced handle. When using it, keep in mind that it's optimized for Gamegenic sleeves. If you use sleeves from other brands, it may affect how much you can fit and how well everything works together. To maintain the Game Shell, simply wipe the exterior with a damp cloth from time to time. Avoid exposing it to extreme heat or sharp objects to keep the nylon and EVA Foam in good condition.
