The hardware maker HORI once again produces a Taiko no Tatsujin product. With the expected released of Don To Katsu no Jikuu Daibouken (3DS2) on June 26 2014, the Bachi-pen set pictured above will be released on the same day.
A prominent feature of the Bachi-pens is their much sharper tips, compared with the officially bundled ones. The set also comes with a Taiko no Tatsujin mat, with anti-slip designs, to hold up your (3)DS steadily.
