Advertisements that businesses stick on your gate or place under the windscreen wiper of your car. The kind you shape into a ball and throw away without even considering reading about the product or service being advertised.
When I got home from work today, my entire gate and fence were plastered with bin fillers.

I found a bin filler stuck on my bin today. Seems like they're starting to understand how this works.
