Petzl's Parallel semi-static rope. The diameter is 10.5mm, and the length is approximately 9m. I used it about 10 times for tree climbing. It hasn't been washed, so there is dirt. Also, I've marked it to indicate the rope length, so the rope doesn't look very good. The rope itself only has some fraying, so it can still be used for things like stream fishing, as a foothold for mountain climbing, and other camping activities. *This is a non-stretch rope, so it does not have a shock-absorbing effect. It is not suitable for climbing, etc. Please purchase only if you understand that this is a used item.
