These Bouldering Problem numbers are not intended for use as climbing holds. They are designed to replace route tags on your wall to label the difficulty of boulder problems. Though they are strong enough to be climbed on, the bolt location could potentially lead to spinning.
With our Lifetime Warranty, identifying your boulder problems with these numbers is a one-time investment.
Measures: 3-1/2" tall x 3/4" standing off the wall.
Numbers 0 through 12 are available individually or as a full set.
