Tactile products are always a favourite and will help you cope with stress.
They are an excellent addition to any office space. Some modern offices aren't really designed for much movement, and a stress ball can help tremendously to reduce your stress at work!
Whatever tactile product you end up choosing, the most important thing is to not leave it at home! In your hand, it is a valuable tool. However, don't be caught without one in your pocket, briefcase, purse, or on your desk.
You just never know when you'll be caught in a situation where having something to play with will enhance your productivity so dramatically as a stress ball!
