Small cam with a dual-action design, perfect for climbing. - Type: Cam - Color: Black/Green - Size: 0.75 - Retail Price: ¥12,980 Thank you for viewing. This is a Black Diamond Camalot C4, size 0.75. I purchased it new and took it to the crag, but I haven't used it for climbing. I set it up once for testing, so there are small scratches, but I haven't put any weight on it. Please consider purchasing only if you understand this.
