Allgäu Holds - Sandstone Incut M (Climbing Holds Set) 10 climbing holds from Allgäu Holds, made in Germany. User-friendly ledges with generous undercuts - grab them before they're gone! The Incut M comes from the sandstone series and is inspired by the appearance, grip, and production of climbing holds in the Elbe Sandstone Mountains, the Palatinate, and Fontainebleau. The climbing holds are available in white, blue, purple, dark green, and neon colors, but are not UV-resistant. This means that outdoor use may lead to discoloration of the climbing holds. However, this does not affect the stability of the holds. Screws and nuts are not included and must be ordered separately.
