It's a good thing to have tags on things that say If Found Lost Or Stolen Please Return To... Like your dart case for example. The Smartass Darters Society would like to step up and make sure everyone gets where they need to be along with their dart case by providing Lost and Found Dart Shirts in many styles and colors to the dart players in need of emergency identification.
These shirts also lend themselves to customization. For example, Joe's Darts Pub could have these designed to say "If found lost or drunk please return to Joe's Darts Pub" along with the address and phone number of the venue, thus ensuring that any and all dart players that may get lost or drunk will be returned promptly.
Consider safety. Consider these dart shirts.
