HarbingerRefillable Chalk Balls, Comes Full, Produces Less Dust Than Loose Chalk, Greatly Improves Grip For Weightlifting, Doing Gymnastics, Rope Climbing, and CrossFit

We purchased these to use at my daughter's cheer gym. They don't have air conditioning in their Florida gym so it is very hot and humid. When stunting, the bases were having a problem holding onto the girls as everyone was sweating. I purchased these in hopes of having something small and subtle for them to use before stunting. They are the perfect hand size and produce enough chalk without making a mess like a traditional chalk bowl. It is also easy to refill.

Even though this more expensive than the chalk cubes, I love this product.So I obviously use this for big pull lifts but when my callouses are on fire. If you open the pouch and rub the ball across your hands it soothes the callouses, and keeps you going.

A great buy. It's less messy and more efficient when applying it. The only thing I would like is if the chalk balls had a package to put them in when we actually break them in. I had to utilize a little ziplock bag to keep it from spreading chalk all over my bag.

Not durable, thinner than panties.

Its chalk in a sock. I've bought theses a few times and they work great. These chalk balls keep the mess to a minimum and the chalk is good qualtiy. I wouldn't try to refill them though. The socks don't open up that much and its hard to get anything into them.

The chalk inside is a solid ball. Had to smash it against the floor for 5 minutes before it's usable. After I got the chalk loose, the sock worked as expected. It lets just enough chalk out so that my hands can be coated while not leaving a mess everywhere.

Long lasting and doesn't break up. I took the chalk out of the socks and use the ball itself. I use one for my hands and the other to chalk a barbell, pull up bar or what ever I need to grip. I honestly love it. But seriously, the socks are worthless.

My gym doesn't let me bring in proper chalk in a tupperware so i use these instead. They work best if you crack/crunch the balls up first. My grip has increased tremendously and I like using chalk much better than straps as it allows me to continue to build my grip strength.
