My coworkers keep "borrowing" my pens, but not these. The MIND YOUR JIZZNESS one got a laugh from the whole office before they handed it right back, and honestly the 1.0 mm black ink writes smoother than most of my regular pens.
The jokes crack me up every time I use them at my desk, and the 1.0mm black ink writes bold enough that even my boss noticed the PEN 15 one. Nobody’s dared to borrow these yet, which is exactly the point.
The 1.0 mm tip writes smoothly and bold enough that the jokes are impossible to miss, which is the whole point. These have survived a week on my desk without anyone “borrowing” them, so they've already paid for themselves.
