This is a Million Strand loop string for Kyudo (Japanese archery). Free shipping! Instant purchase is available! Raw Material: Mercury2 Thickness: Thick Standard: 4-sun-nobi (a bow length) Compatibility: Koyama style String Color: Brown I used to shoot a 4-sun-nobi bow, but I've switched to a 2-sun-nobi bow due to changes in my shooting form, so I'm selling this. The raw material is brown, and it looks so good that you can't tell the difference from a synthetic string. A string maker I know has replaced the serving and maintained some parts of the string, so it's in as good condition as new. Each strand of the raw material has been wax-removed and re-waxed, so there is no fraying at all. I used it with a Koku-shin bow of 15kg. There is no widening of the string loop, which is typical of Million Strand strings. There are no problems with its use. Currently, Million Strand strings take about a month to be delivered, and the quick delivery option costs about 15,000 yen, so it's a great deal considering the time factor. Price reduction is accepted. I want to avoid any trouble, so please feel free to ask any questions you may have beforehand. Therefore, cancellations after purchase are not possible.
