Have fun together with your friends or alone with this amazing jumping ball! It is easy to use, you just spin the ball along the floor with one leg and jump over the rope with the other leg, then put one foot through the ring, turn the ball over the rope and then jump over the rope. You'll get a lot of laughs while hopping around the house or outdoors... and then it's not just a fun game, it also keeps you in training! Ball salterina Plastic LED Lights Measurements: 32 cm 15 cm
