[Create Your Own Rhythm]: Everyone on stage can start and play, regardless of ability. Although difficult to learn at first, when someone figures it out for themselves, they can use it to create a variety of different rhythms, possibly uniquely their own. [No Complicated Way to Play]: The instrument contains small iron sand inside and produces a clear and pleasant sound when shaken. When the ball is shaken, it makes a "crunch" sound, and when it hits the ball, it makes a "knock" sound. It can be freely combined in just two steps. [Unbreakable]: The outer material is made of high-quality ABS plastic for protection and durability. Strong, unbreakable braided climbing ropes are used to secure the ball and extend its life. [A Good Way to Relieve Boredom]: When people play, they can relieve stress, eliminate boredom, and improve brain flexibility. Therefore, it can also be used as a great toy for children to develop their sense of music. [Best Gift]: If your family or friends feel bored or stressed lately, this shaker is a great gift for them, which will bring them the fun of playing and a positive experience.
