These are mybachi (drumsticks) for Taiko no Tatsujin. I bought them on Amazon in April of this year for 12,000 yen, but I got bored of them soon after, so I'd like to sell them. There are small scratches on the tips, visible if you look closely, so please refrain from purchasing if you are sensitive to such things. I've used them about 10 times and kept them in a mybachi case, so I don't think there's much deterioration.
