So you get tired of drinking coffee from the tiny Styrofoam cups that they have at work and you bring in your own cup. It can hold more coffee, keeps it warmer longer, and just looks nicer on your desk. One of the subtle things that make your day just a little bit better.

Now, after a week or so you come in to work and cannot find your cup. After searching the office you find it dirty in some conference room. Someone else had actually used your own very special cup. You may contemplate never using it again, throwing it away and just buying another.

All this could have been avoided with this secure coffee cup with a lock in it. No, it does not lock out anyone from getting a hold of the cup, or stop anyone from pouring anything into it. But, when you remove your special key it renders the cup useless since the key plugs a hole that keeps the contents from running out.
