Perfect Ovalis designed as a true, milled oval shape. This oval shape is flat through the center and is the most like the shape of your fingertip giving you a very natural and relaxed fit.
Power Lift 1/4 helps increase loft and length of release to the target. The finger pad has a flat edge and smooth surface for a sharp, clean feel.
