Finally, a NetChecker with style! Adorned with a cute pose of Robbie, the Robo-Pong mascot, this NetChecker is both functional and stylish! The center slot measures the height of the table net while the corner notches measure the maximum thickness of the rubber on your paddle (4mm for sandwich rubber, 2mm for ordinary pimpled rubber). This tool is indispensable for all table tennis players. Made from durable white ABS plastic and printed in color on both sides.
