Table tennis players and coaches, this 120-ball box of Donic-Schildkröt TT-Club balls is exactly what you need for serious training! These are the Poly 40+ balls that have replaced celluloid - they're more environmentally friendly but still deliver that same great performance you expect from quality table tennis balls. As the inventors of the table tennis ball back in 1896, Schildkröt really knows their stuff, and these training balls prove it. The bounce is consistent, the roundness is perfect, and they're durable enough to handle hours of intense practice. The white color gives you great visibility, and the 40mm diameter is the official tournament size. Whether you're running a club, coaching a school team, or just want a massive supply for home practice, this 120-ball box means you'll always have spares ready to go. I've used these for both casual games and serious training sessions, and they perform beautifully - no weird bounces or easy breaking like you get with cheap balls. The price per ball is fantastic when you buy in bulk like this, and the quality is exactly what you'd expect from a German brand with over a century of experience. If you're tired of constantly buying new balls because the cheap ones break or lose their bounce, this 120-piece box is the smart investment that will keep your games going strong for months!
