This is a new, unused item that I purchased. This product is 8mm thick and 0.76m long. Please read carefully before considering a purchase. I have two of these, and if you want both, I'll sell them for 9,000 yen. Please comment if interested. Thank you. The Teufelberger Ocean Polyester is a high-performance prusik cord (hitch cord) primarily for tree climbing, featuring a blend of polyester and aramid (Kevlar) cover for excellent heat and abrasion resistance. The 8mm/10mm diameter, e2e (end-to-end eye splice) type is the mainstream, known for its high safety and durability, and designed to withstand friction heat.
