Well, with these customizable Droplet Stress Balls, it could be any of the three! Because there are three different colors, the promotional Droplet Stress Ball can be used for anything from blood drives to automotive repair shops to water suppliers. It's hard to find a promotional product as interchangeable as the branded Droplet Stress Ball. You can give these away at conventions or hand them out to customers after they receive your services...but either way, they'll be getting a fantastic stress reliever! Put your phone number on the black one to ensure your clients stop in for an oil change, and make sure to customize some dates on the red one so blood donation goes off without a hitch. First-timers at the blood drive might appreciate having something to squeeze if they're a bit nervous!
