DMM quickdraws. These are an old model, used for about 5 years. They were used for alpine climbing, so there were basically no falls, but please consider that they may have deteriorated. There is no tag indicating the year of manufacture, so please judge from the images. Suitable for A0, spares, or as a "throw-away" carabiner. Please use them at your own risk. Size: Carabiner: Approximately 95mm Sling: Approximately 100mm Weight is unknown as I don't have a scale, but they are light.
