- Color: Brown - Length: Approximately 10m AI assessment, but there's a difference of 10m to 30m even for similar items ( °_° ) I'm listing several similar ropes, but the AI's length estimations vary too much. I think it's best to look at the photos and judge the length yourself based on the weight. 3m weighs 1 kilogram. These are long-term storage items, and they may be slightly dirty as they were sometimes kept outdoors. Thank you for looking. Discounts available for bulk purchases.
