Super useful tool for building and maintaining good skin, especially when local rock is not an option.
Last year, I used my set to prepare my skin for a trip to Västervik, which allowed me to climb from day 1 without worrying about damaging my skin on the Swedish granite. Since then I have been using the holds to keep my skin in good shape for projects on volcanic rock types that I cannot visit frequently, allowing me to take advantage of each session outside.
