This innovative product, which covered 2-3 sizes with a single cam, is no longer in production and is difficult to obtain. Link cams with a wide range are useful when you want to reduce the number of cams you carry but are unsure about the sizes, such as on ridgelines, in stream climbing, on variation routes, and in the snowy mountains. There are scratches and dirt as it was used for stream climbing and winter wall climbing. I also used cam aids, so the wire core of the stem on the #0.75 has a slight bend due to static load, but there are no problems with its operation, and it has not received any falls or major shocks. Please purchase with the understanding that this is a used item. Climbing is a dangerous activity, so please use it at your own discretion.
