I purchased this and stored it unopened. I am selling it because I have not used it. A convenient set of 2 nylon tent ropes with carabiners. A rope ratchet that allows you to stretch the rope taut simply by hooking the carabiner and pulling. The rope is woven with reflective material, making it safe even in the dark, such as at campsites. It seems useful in various situations, such as securing luggage, setting up tents, and hanging luggage. - Model: zak-80839-black - Quantity: Set of 2 - Material: Nylon - Accessories: Carabiners Thank you for viewing. Rope thickness: 4-4.9mm
