Recently found in the basement a souvenir from the Wisconsin Dells for the Wisconsin Deer Park attraction.  The cap comes off easily but is still really solid in its sealing.  Some original toothpick are still in it (but I wouldn't use them-don't know how old they are.  You can also use it for carrying extra pills, needles or even a smaller cigarette.  Couldn't tell you about the last one, I quit smoking over twenty years ago.
