Black jute rope · 5mm double-ply (treated)A bold black double ply jute rope from our own Anatomie line, hand treated and ready to tie. Double ply ropes are more stable than single ply ropes, making them popular with beginners, as they require less maintenance. At 5mm this rope is thinner than the 6mm thickness most shibari rope comes in: this makes for smaller frictions and a lower profile against the body, which suits smaller frames and finer, more detailed work.
