This is a set of 9 foot holds. They are made of plastic and produced with a 3D printer. 【Product Features】 "I don't want to limit the holds I bought to just foot holds..." "Instead of buying catches to attach to volumes and crimps, I want holds that are more 'grippy'..." For those people, we have created affordable foot holds and catches. 【About Friction】 Each hold has a side with friction and a side without. Friction can be felt to some extent even without chalk. By using chalk or PD9 in combination, you can feel sufficient friction. ⚠️ Important Notes for Use Compared to general resin-molded or urethane holds, the strength is inferior. The manufacturer himself uses them daily, and no major problems have occurred to date. Over-tightening the screws will cause damage. Please be careful not to overtighten when installing. Please use at your own risk.
