For fun pick-ups, our MasterPro Ball Tubes are among the best! Heavy-gauge rubber ends won't crack. A rubber band at the end holds balls in place when the tube is laid flat. The 48" tube holds 21 balls; the 36" junior model holds 15 balls. Designed to hang on the side of a teaching cart. Each MasterPro Ball Tube includes a shoulder strap. Extremely durable.
