This 20-piece counter display is complete with four strengths. While this reader is designed with the golfer in mind, having an attached ball marker, a place for 3 tees and a pencil, it is also great for anyone on the go. The neoprene case has an included carabiner to attach your readers anywhere. A classic, thin frame design, a convenient on the go protective case, makes these readers the perfect accessory. Available Strengths: +1.25, +1.75, +2.25, +2.75
