This is a single item sale of the string for spinning tops, suitable for models like the Tsubame and Hibari. This string is specially ordered for spinning tops, with a thickness of approximately 3.5mm and a length of about 130cm. It's not too thick or too thin, making it easy to wind and perform tricks. (Due to the nature of twisted strings, there may be individual variations in thickness.) It can be used with our products such as the Tsubame, Hibari, and Hayabusa, as well as many other spinning tops. This is a right-handed string, designed for those who wind clockwise. Using it counter-clockwise may cause the twist to unravel, potentially damaging the string, but this is part of the product's specifications.
