Ice Cream Pint Lock

Due to roommates that didn't quite understand my displeasure at my consistently disappearing ice cream, I had to resort to this. Not a gag, it is actually is designed with the intention to work. Though I suppose that since the container it is "locking" is made of waxed cardboard (which can be deformed a bit) it won't keep out a serious professional penetration attempt. I found that it sends a warning message, sort of like one of those little LED's you put in a car to give the appearance of having an alarm.
