If you live in a world where you have to worry about your coffee being stolen, you are probably in the wrong place to live but here’s a Lock It Cup just in case.
A cup that is designed for people who share facilities at their work place, such as the kitchen. The cup has a hole which prevents most people from using it. Only the owner of the cup can use his shaped key to close the hole, pour the coffee and enjoy the drinking.
