Next month’s October issue of Kirara MAX will come with a 「Yamada makes a mistake repairing bocchi」 pick.
It’s a versatile teardrop shape with a very sharp jaw.
The harder you practice on the guitar, the more Bocchi will regain her original appearance.
We hope that everyone from beginners to experienced players will get their hands on one.
