This is a Himuka loop string for Kyudo (Japanese archery). Raw Material: Mercury Length: 2 sun extension Color: White Condition: Good This is a Himuka string from Moriyama Kyugu store, which has a history of over 20 years. It was a very easy-to-handle string. The string loops haven't widened at all, they're still tight. I used it with a Koku-shin 15kg and a Bamboo 15kg bow. It's still perfectly usable. I had it waxed and lightly maintained by a string maker I know. I can add more pictures if you request them in the comments. The serving is a rare blue color. You can change the color, but it will be an additional 200 yen. Free shipping.
