This leaflet holder has a weatherproof (flip top) lid and is designed for use outdoors. The single pocket is sized to accomodate business cards in a landscape format. The depth of the unit is 32mm which suggests a capacity of 64 cards depending upon paper thickenss which highlights its role in holding a pile of business cards to be dispensed to customers (on a self serve basis) one at a time. The unit is made from crystal clear ploystyrene, has holes in the back for wall fixing and special clips are available (at extra cost) to enable it to be hung from a car window. Business card sizes are not covered by the ISO 216 standard but tend to be sized around 85mm by 55mm which is similar to a regular credit or debit card.
