To claim it unique is not only because it is
the world's oldest condom (dating back to 1640), but also it is reusable (who is able to to recycle nowadays' latex ones?)
[It] is completely intact, as is its orginal users' manual, written in Latin.The manual suggests that users immerse the condom in warm milk prior to its use to avoid diseases.
The antique, found in Lund in Sweden, is made of pig intestine and is one of 250 ancient objects related to sex on display at the Tirolean County Museum in Austria this summer.
