Professional Baseball Grip Enhancer. Introducing the new and improved King Stick. One of the leading pine tar sticks. We have transformed the pine tar stick to be fully eco friendly while enhancing overall performance. Hitters know the feel of your bat is important. King Stick helps improve your grip while maintaining excellent feel for your bat! We as well want to give back with every stick purchased to some of the proceeds going to St. Jude Children's Hospital.
