The world's most pure magnesium carbonate in a refillable chalk sock. Spider Chalk's Chalk Balls are the perfect size pouch to fit in your hand, climbing bag or gym bag. Each chalk ball is filled with 3oz of ultra-pure Spider Chalk powder.
Lasts Longer - Pure chalk lasts longer on your hand and has better grip with superior drying ability. That means Spider Chalk balls last 2x longer than any other chalk.
Refillable - With an elastic drawstring and heavy duty clip, our Chalk Balls will last through repeated refill sessions. This will be the last chalk ball you ever buy.
More Chalk - Spider Chalk Chalk Balls are 3oz each which means more chalk per pouch.
- Pure Chalk - Other chalk balls use cheap, generic chalk. Spider Chalk uses the most pure chalk on the planet.
