These Titanium Blackline® Rattle Balls are completely unique items! Replacment balls for the Rattlebells, these balls are hollow with heavy internal balls encapsulated in them. With movement these internal balls "rattle" resulting in a effect that passes throughout the shaft and through the entire item! Perfect for tongues, nipples and genitals!

These balls are designed for internally threaded stems (either 1.6mm thick stems or 2.4mm thick stems).
