2 soft and grippy neoprene catch balls with adjustable wrist straps. The Velcro surface is securely stitched to the neoprene and cannot tear out, unlike what often happened with plastic catchers in the past. The set includes 1 Velcro ball. The ball is thrown back and forth and caught with the Velcro catcher. The ball sticks to the catcher. The game is a lot of fun and also helps develop hand-eye coordination and throwing technique. It's great fun for both young and old. As always with Schildkröt, the complete set is packaged in a resealable mesh bag, making it easy to store everything neatly after play. This way, you can easily find the ball for the next game. Warning: Remove packaging completely before giving the product to children. The over 100-year-old German brand Schildkröt is known as the inventor of the table tennis ball. Today, Schildkröt offers a very extensive collection of fun sports in addition to table tennis and is considered a market leader in this field.
