Not that I am advocating breaking the law. But if one wanted to sneak a can of beer where those things are not allowed then Lolo Lids are a clever way to evade the long arm of the law or security.
The lids snap on top of almost any regular-sized canned beverage. Whichever beverage you want and then attach to a coffee cup from your favorite java place. Two cups might work best to hold the full can.
Just make sure to act natural when carrying it. It’s a trick even some actors haven’t pulled off.
