Black 5m nylon strings for kendama and white 5m nylon strings for kendama. They are cut a little longer. Please cut them to your preferred length. I cut mine to about 65cm. Those who want to do juggle tricks or string tricks might want to cut them a bit longer. These strings are made of the same material as the strings used for Japan Kendama Association kendamas. You can also use these strings to participate in Japan Kendama Association competitions. Buying strings at a kendama shop costs about 160 yen per string, so I think it's a great deal to be able to buy strings at this price. I will ship them in an envelope. Thank you. Also, if you purchase additional kendamas, kendama strings, bearings, or beeswax wax that I have listed, I can offer a discount. (These items will be shipped together with this product.) Please consider it. Have a nice kendama days‼︎
