This classic parking Penalty Charge Notice design brings a double whammy approach to busting the bad parkers. Not only on approach do they think the 10cm by 10cm square sticker is a parking ticket, but on approach they realise that actually, someone secret has called them out on their shocking antics of parking in disabled bays. 

Each sticker is individually cut, perfect for the door side pocket of your car or the glove box, readily accessible to slap on the window or windscreen of that parking wanker who is taking a disabled bay without just cause.
