I recently ordered some refillable paint pens from Art Primo, and this was in the box as a freebie. It’s the exact size, shape, and color as a cigarette, and among a dozen real cigarettes in a pack it’d likely pass any search completely unnoticed. It took me a minute to figure out its nefarious purpose: If you get caught in the vicinity of a fresh tag, after all, it’s best not to be found with a marker on your person. They’re manufactured by Germany’s On The Run, but you won’t find them on their website. The one I got was gold; the silver ones below were photographed by Flickr user $30,000.
