This is a reusable condom dating back to 1640 CE.  It is made of pig skin and appears to have a small draw string to hold it in place.  It is completely intact, as is the original users manual written in Latin.  The manual suggests that the users immerse the condom in warm milk prior to its use to avoid diseases.  The condom was found in Lund, Sweeden, and is on display at the Tirolean County Museum in Austria.
