I purchased these here, but unfortunately, they didn't suit me, so I'm putting them up for sale. I apologize to the previous seller m(_ _)m These are wonderful bachi, so I hope someone who can use them will buy them. Opening: Approximately 79mm Total Length: Approximately 159mm Butt: Approximately 23mm x 23mm Weight can be adjusted in 5g increments from 65g to 105g. The handle is non-slip and easy to play! I've tested them about twice, so please understand this before purchasing m(_ _)m
