This set offers 1" to 2-1/2" wide pinches, which are on the narrow side of grips when it comes to pinches. This set has a very small footprint, so they are ideal for filling spaces on your home wall to maximize your training options.
You can set these as edges, too, which offer depths of 3/4" to 1-1/2".
You can't go wrong with this set, as you can use them for a foothold if you are a beginner or as a grip for the advanced climber to get strong on. There is a lot of grip variety, not just in widths but in the nuances of the shapes feeling so much like rock.
