Check out the benefits Of CoolStuff 100% magnesium carbonate chalk powder ball with white chalk refilled and resealable bag.

Weight: 3 oz

CoolStuff Chalk Ball consists of premium 100% pure Magnesium Carbonate Chalk. The chemical formula of sports magnesium carbonate is 4MgCO3 * Mg (OH) 2 * 4H2O. Unlike calcium carbonate, which also has a good hygroscopic effect, magnesia binds your skin fat and therefore significantly increases the friction between your hands and the projectile.

CoolStuff Chalk Powder Ball comes in a refillable protection bag.

The protective bag allows you to store your ball and keeps your gym belongings clean.

CoolStuff Chalk Ball produces less dust than a loose chalk and lasts significantly longer. This stuff really works and doesn't make a mess. It's cleaner than your dirty sock filled with chalk!

CoolStuff Chalk Powder Ball is used by climbers, gymnasts and lifters worldwide. It greatly improves your grip for weightlifting, rock climbing, rope climbing and gymnastics.

Before usage, the Chalk Ball should be crushed by your hands or feet. The crushed chalk will stay inside the outer ball and from now on your hands will be chalked up through the porous fabric.

Please use hand cream after using the Chalk Ball. This will protect your skin from drying out.
