"I don't want anyone to think I'm cashing in on the Rugby World Cup. Those words, as such, do not appear on the mugs."
Kan says the mugs are a statement about free speech. "At a time where everything seems to be touchscreen, I like using a medium that stands up to hot beverages.
"If you plan to abstain from coffee, the mugs have a revolutionary new multi-function which also works with cold drinks.
"And if you buy both mugs, and don't eat a thing for six weeks, there are also amazing weight-loss benefits."
The mugs go on sale from today, either from raybonkan.com or Trade Me.
