We String It is proud to bring you our hand made pine tar! We all know that tack is important. We designed this pine tar/ rock rosin blend specifically for your bats. This pine tar & rock rosin blend is the perfect amount of tack, wherever a touch of tack is needed. Simply pour a small amount out of the container onto your pine tar rag and spread evenly, or use your finger and dab wherever additional tack is desired. Store flat in a cool, dry place when not in use. Comes in a 4 oz. in a plastic jar with screw top lid.
