How do they work? It’s pretty simple. You open the brochure, and your video comes on. Each video card is capable of holding from 30 seconds up to 8 hours of video. You will be able to customize the size, color, shape, screen size, etc. The design of the brochure is completely up to you (or we can help you too!). Let your imagination go wild because we can handle any size/shape from a box to a folder or even a book!
