We've started handling non-slip rubber sleeves for shamisen Bachi. Not only do they prevent slippage due to sweat for longer periods of time, but they also round off and soften the corners of the Bachi. They can be used with various sizes of Bachi including Tsugaru, Nagauta, and Jiuta-Minyou, and are available in two colors, brown and transparent. They're recommended not only for concerts, but also for long practices.
