As should
be obvious from the rather high price, these are very high-end
nipple clamps. They are made mostly of solid brass giving
them an attractive gold color. The tension on these clamps
is adjusted by turning the black cylinder at the base of
the clamp to slowly increase or decrease the pressure. This
mechanism allows for very precise, controlled tuning of
the intensity. The look, feel, and function of these clamps
are all top quality, and they are prized by those who have
had a chance to work with them.
These
clamps are manufactured by Spartacus of Oregon. Their part
number is SPF-51. We shopped around online for this item,
and the lowest price we could find elsewhere was $126.
