Chromite Russian ball

It is a Russian ball with a mineral sand (chromite sand) of chromite in the plastic ball. Chromite sand has a heavier weight than normal sand, it has a solid center of gravity while reducing the amount of sand in it, and it is superior to the technique of stall system which stops especially with forehead and feet. Because the grain of the chromite sand is very fine, the moving sound is still quieter than the Russian ball. Moreover, because it has high fluidity, there is comfort to sink into the center of the palm at the moment you catch it. The outer shell is also slightly thicker and harder, making it difficult to dent when grasping. ★ About color Pictures may differ from actual colors.
