Blackline Internally Threaded Rattleball

PVD coated G23 surgical titanium internally threaded rattleball.

The blackline rattleball consists of a 6mm diameter outer surface with a heavy metal spherical insert imprisoned within the titanium casing.

The encapsulated ball is three times heavier than the titanium shell and becomes agitated with the slightest motion, causing resonance throughout the ball and barbell on which it is worn.

The resultant trembling effect passes through the hollow shaft of any internally threaded stem (i.e. barbell, circular barbell) and percolates through the body in exciting ripples of pleasure.

The rattleball is compatible with internally threaded jewellery only.
