Display cabinets are a popular visual merchandising device in shop windows. Products are displayed on shelves and are visible to passers-by and can be accessed from inside the store. A Contra Vision window decal can be added to the outside of the cabinet to provide an additional visual effect. If the cabinet is well illuminated, then the graphics become highly see-through and the products are visible inside. Switch on and off the light and you can create a diverting impact on shoppers.
