For those of you who work in offices and are in a constant need of a boost of energ, a personal mug is perfect. But what happens when other people use it without even asking and you always have to wash it although you never used it?

Thank God for Plug Mug! This is a brilliant device that has a hole in it and a plug to keep the liquid from pouring. And if you take the plug off…..ta ta: no one will be able to use it anymore. Plus it has a suggestive design (a “stop” sign).

Clever and cheaper than having to spy on your colleagues!
