We all know that no means no, but sometimes, there is a need for the Avichai Tadmor NO Sign. That's because when it comes to our much needed technology, people are often quick to negate the rules.

If your workplace has a strict policy on no cell phones, cameras or smoking, then you'll find this Avichai Tadmor NO Sign quite handy. Simply confiscate the item that's been forbidden and slip it under the elasticized badge. It's a great visual reminder that we should all abide by the guidelines set.
