Chalk Rebels crystal chalk sample packaging

We are currently testing a promising alternative to traditional white powder chalk and even liquid chalk. We call it "Crystal Chalk". It does not contain magnesium carbonate and comes in a clear gel form. We believe it is especially promising for indoor bouldering and home training. It leaves absolutely no trace on the rock yet still dries out your skin like traditional magnesium-carbonate based chalk.


We sent out free samples of crystal chalk in 2020 as part of our product development process but have currently stopped doing that. The product is available for sale now. We do send out new samples from time to time, so if you are interested in helping us improve our products by testing samples, get in touch!
