the lock cup
Perhaps your workplace isn’t as polite and well-mannered as mine is. Maybe you deal with rude coworkers who eat your lunch and steal your coffee mug. If keeping your coffee mug for your usage only is an issue, this is a handy dandy little mug designed to render itself useless to anyone but you. Just take the hole out of the Lock Cup when you’re not around, and plug it back up when you’re ready for a hot steaming cup of joe.
Guaranteed to mess with your co-workers heads!

hehehe that’s nifty.
He he that is very cool. Guess a cup with a hole in it isn’t of much use!
Pretty cool. Now if they would just invent a locking box of donuts to keep my office mates grubby paws off…
