Using your Gamegenic Game Shell 250+ is a breeze. First, unzip the case and arrange the two adjustable dividers to create compartments as you like. You can put your double - sleeved cards, tokens, dice, or small games in these compartments. If you want to carry it around, attach the adjustable shoulder strap. When you're done using it, just zip it up. Remember, this case is optimized for Gamegenic Sleeves. Sleeves from other brands might affect the capacity or compatibility. To keep your case in good condition, clean it with a soft, dry cloth. Avoid exposing it to sharp objects that could damage the nylon surface. Store it in a cool, dry place when not in use.
