One of our favorite promotional items that are perfect for day spa’s and salons is the stress ball. Think about it. You go to the day spa to relax and let all your worries go away. When your sitting waiting for your service why not play with a stress ball. And if the salon is smart they could give out some discount stress balls to their clients that have their name and number on it. These things are even more effective than business cards because clients keep them around and others see them too.
