Any size of business or individual stands to benefit from these small yet versatile pieces as you build a relationship with your audience hence easily promote an event you may be having, share a map to your new shop location, display your items or services along with prices, and so many more. They are small and easy to hand out or place strategically so that people pick them as they mill about a convention or trade fair, yet big enough to hold a summary of vital information you wish to share.
