This adult pencil case design from Happy Jackson is a humorous and suggestive take on an office classic. The yellow PVC stationary holder also carries the slogan explicitly stating the pens inside are engaging, or will be engaging, in a group coital act. The invitation is also open to pencils, as it appears the sensual party is non-discriminatory. It would be unsurprising to find erasers, or even protractors in attendance.
The black print is on both sides of the cylindrical case. The Happy Jackson pencil case is ideal for anyone with a naughty sense of humor, ideally over the age of consent. It's also an incredible way to start a conversation in class, but might be better kept inside a drawer at the office place unless you work in an (extremely) open environment.
