These are crampons I use frequently. I maintain and paint them after returning from the mountains, so rust is not noticeable. The rubber crampon bands broke, so I attached a new band to the back that I had on hand, and also attached a new Evernew wrap-around band. I've made modifications for my own use, such as left/right indicators, to prevent mistakes. Please only consider if you don't mind these modifications. For low mountains, summer snowfields. Suitable for Hakuba Snow Valley, Harinoki Snow Valley, Tsurugizawa Snow Valley, etc., and also for low mountains in winter. 12-point crampons are absolutely essential for winter Alps. Advantages of 4-point crampons: Compact. Lightweight. Sufficient grip is secured for low mountains in winter.
