These Rhythmic Gymnastic Balls are called Galaxy because they have a sparkly surface. They are certified for competition use by the International Federation of Gymnastics (FIG). These large, 180mm-190mm, balls are suitable for older children and adults. They weigh between 400g and 410g.
The balls are made from Tecnocaucho. "Tecnocaucho" translates as "techno rubber" and is a special rubber, exclusive to balls of this type, that is engineered specifically for sporting use.
Rhythmic Gymnastic balls are also great for training contact juggling body rolls as their large size make rolling moves easier than with smaller stage balls or acrylics.
These gymnastic balls are usually delivered partially deflated (you will need a football pump adapter to inflate).
