Owner's eight-strand thread with no random Japanese name Kizuna meaning close relationships and strong bonds forever! It is made entirely in Japan of very strong polyethylene fibers, with a unique structure between them that creates a tighter knitting, which does not loosen over time, as opposed to the usual structure used in yarn making. The difference is that half the fibers follow the opposite half and the results are impressive. It is a very strong thread, with enormous strength and high abrasion resistance. It is light, floats in the water, has a very light green color and is ideal for long shots. It is very flexible and not easily confused. It has a long shelf life as it is resistant to moisture absorption and sunlight. At the same time it is environmentally friendly and does not release harmful substances if it burns.
