The Practice Stick ball retriever is designed to fit inside your golf bag, unlike conventional shag bags, right along with your clubs. When you need to shag balls around the green, trap, or hitting net, the Practice Stick is a must! Simply place the open end of the Practice Stick over the golf ball and 'click' the ball in. The Practice Stick will hold 24 golf balls. To empty, simply release the spring loaded lever - out come the golf balls.
