I had to add some camo painting to not make it a dead giveaway. It is 3"x3" and that is a bubble level in the corner.
No. Creative guess, but no. I am not going to drop hints just yet, but will describe it better by telling you what it doesn't have. It uses no power and has no hidden parts. You can see it all there except the printed label on the lid, which is covered up. The label has the name of the item, instructions on its use and the manufacturers name and info on it.
