The Hazmat team found 12-15 packages covered in the substance. Three employees were treated after coming into contact with the unknown chemical, which was originally believed to contain methanol.
Investigators later discovered the source of the ooze was a bottle of K-Y Intense Arousal gel, which spokesman Tony Robinson said contains ingredients used "to intensify sensation."
Postal officials didn't say exactly where the package of personal lubricant was headed, but said it was sent to someone "in the entertainment industry."
Robinson said that they will follow their usual policy and contact the sender with friendly advice on how to better secure their packages to prevent future incidents.
