These original keychains with a minimalist design will delight climbing enthusiasts. Inspired by our climbing experience, we've designed cracks that look as real as nature to always have a piece of the mountain at home. The concept is simple, just place the different nuts in the cracks to store your keys. Two attachment systems are included to hang your KeyHolder on your wall (adhesive or screws). Do not use the "nut" keychains during an ascent. These are keychains and are by no means capable of stopping a real fall (0 kN).
