While a standard card display will usually hold between seven and ten cards, depending on the size of the unit and what's inside, custom designed models can hold more or less. Display cases with several card slots can hold more than fifty cards idn poker, so you'll want to consider how many different types of cards you normally sell before buying one. The larger the display case, the more potential it will hold all your seasonal promotions and deals. A nice addition to a larger display case is a pop up tray. These trays allow customers to easily see their promotional items when they arrive at the store, saving them time and energy as they scan the aisles for cards and other goods.
