The
first barbell is an example from
our studio. Note that the post
itself is not threaded. This is
an example of an internally
threaded bar. The threads are on
the ball instead of the post.
This allows for comfortable
insertion without damage to
tissue. Also note that the bar
contains no gap between post and
ball.
This
is an example of an externally threaded barbell.
Notice the sharpness of the
threads which will certainly
damage the tissue upon insertion
or removal of the jewelry.
Material content for the piece is
unknown, and balls are ill fitted
allowing for a gap between post
and ball. Such gaps can harbor
bacteria.
