The new 16A32 TPR Flat Round Markers have anti-stick and extra grip technology to prevent slippage on some surfaces. Designed for all types of training, TPR Flat Round Markers are ideal for setting up boundaries of a field or grid. Unlike a training cone, the ball rolls smoothly over the marker, decreasing interruption in your drill. The TPR Flat Round Markers come in sets of 10 and are available in red, white, blue, and yellow.
