Consider personalized keychains as a promotional item for your business. Everyone uses keys, so why not put your company name or logo where it will be seen every day — on a custom keychain. When marketing your brand to a large number of people, it is cost effective to distribute a cheap promotional item at events like trade shows or conventions. Custom keychains can fill this need. These personalized keychains come in all sizes, shapes, styles and colors. Some of these personalized keychains include can openers, whistles, lights, carabiners, compasses, pill holders and more.
