Chalkness Monster Gym Chalk is dedicated to eliminating moisture and improving the grip of athletes across the globe. This Apex Chalk combo combines 100 grams of finely ground chalk powder with a refillable chalk ball with a unique open/shut slide strap. Most chalk balls are sewn shut, meaning that when you run out of chalk, you have to buy a whole new ball! Not Chalkness Monster, who is dedicated to reducing waste. That's why we designed the unique slide strap to enable refilling your favorite trusty chalk ball. Perfect for rock climbing, this finely ground, 100% magnesium carbonate chalk powder eliminates moisture and improves grip. The chalk ball fits 50 grams by itself. Get the most out of your game! Whether you are bouldering at the climbing gym, practicing your rings routine, or trying to break your dead lift record - make sure your grip is the last thing you are worrying about!
