TWO STONES Climbing & Bouldering Brush with Natural Firm Boar's Hair Bristles and Durable Handle, Climbing Chalk Brush Designed for Ultimate Performance on Climbing Wall Indoor or Outdoor

They do exactly what they're supposed to do--brush chalk off of holds. I like the angle of the brush as well; they work better than the basic wooden brushes that do not have a curve in the handle.

Husband and I have been bouldering for a few years, and this is the first super sturdy thicker brush for climbing holds we've used. Been using for a few weeks now, and it seems it'll last us a long time. Would recommend!

Works as intended and conveniently fits into my dmm chalk bach brush holder snugly. Some bristles break or fall out but not enough to change its performance so no real issue. For two brushes a great purchase!!

Husband was looking for chalk brushes for while he bouldered. These worked great! He was very happy with them.

I'm a rockhound, I use these on wet rocks I'm going to tumble. These are so much better than a toothbrush although for smaller areas I still have to use one. I like these enough I put them and a link on my Instagram, for me to endorse a product that way it has to be great.

These are solid brushes. The bristles have good density and are consistent with a good quality brush. I got the black and orange. The black had black bristles, which were somewhat stiffer. Not sure if that was intentional but its pretty cool. My only criticism is that the plastic above the bristles is thicker than I would like, which makes it more difficult to brush small incuts because it hits the wall when you angle the brush. Two stones if you are reading this cut the thickness of the head in half like the old sublime and you'll have the best brush ever!!

They get the chalk and grease off the hold. Proj gets send after a good brushin

Only wish is maybe that they were lighter weight (they tend to flop around in the holder on my chalk bag)
