A leather stretcher is generally not good at creating stretch as
it produces no downward pull, so the name is somewhat of a
misnomer.

It does however work well at retaining and consolidating stretch
achieved and to this end is used a lot.

Leather, of course, has the irreplaceable sensuous cachet
of feel, smell and looks. Few can resist the temptation of
wearing soft black leather next to their skin, especially next
to such a deliciously sensitive area as the balls.

A good leather stretcher is made of leather that is soft
enough to have a pleasant feel, yet firm enough to avoid
wrinkling up under the pressure of contracting cremaster muscles.
it needs two sets of snaps for adjustment and the snaps
need to be heavy duty. The top edge should be turned over
to produce an edge that offers some comfort.
It is common for sweat to cause sticking to the leather and
this is difficult to avoid. Talcum powder should be considered
when using leather or latex stretchers.

Some use rubber instead of leather, but it is generally
less yielding and more prone to sharp edges.

Neoprene is another alternative. Whilst it is potentially very
comfortable with its combination of soft edges yet firm control
it requires significant pre-stretching to be able to get over the
testicles to encompass the scrotum and this tends to weaken
it as they are usually made using a glued construction. Non
petroleum lubricants must be used with rubber and neoprene
to avoid degradation of the latex.

Silicone stretchers have made a relatively recent appearance.
They are stretchy, able to be used with any lubricant, and
generally comfortable but of course will not produce any
downward pressure, and tend to have slightly less erotic
appeal.

Rubber rings can be used as ball stretchers. It should be noted
that rubber has quite a high co-efficient of friction (why cars
have tyres made of it) so lubrication is important to avoid
excessive skin abrasion. Petroleum based lubricants are
out, and water based lubricants are generally not effective
for long enough, which leaves only silicon.
