This is the official commemorative shuttlecock of the BWF Badminton World Tour Finals. Unlike the regular ones, both the tube and the shuttlecock have a beautiful design. It's a great deal as a set of red and blue. Not available in Japan. Purchased at the shop inside the tournament venue. The Badminton World Tour Finals is a tournament where only the top 8 players in the world rankings can participate, and it has been held in Hangzhou, China in recent years. It's difficult to go from Japan, but it's a very popular tournament where only world-class players like Kodai Naraoka and Akane Yamaguchi can participate. How about it as a souvenir? Individual sales are also available.
