From Hakamata Equipment, a yo-yo accessory manufacturer produced by Takumi Hakamada of Team Yoyorecreation.

Ryo Miyazaki's signature string, "Toru stirring," which combines "flying string" and "ease of sliding," has been released.
The yo-yo is extremely easy to fly, perfect for Miyazaki's modern tricks, where he freely flies and flicks the string, combining it with the yo-yo.
At the same time, we have achieved good glide by using soft materials that make the stiffness that is common in strings that fly well almost invisible.
