Now where do you think these came from? There are a lot to be found of various sizes all over every place I visit. We all walk past them and notice them not.They are clipped around almost every lamppost in town. The signs they once secured long since gone. I suppose technically its theft to take them, but the council will never remove them and if they did would put them in the bin.
They really are litter and being a litter collector I walk down town with a pair of cutters in my pocket. Some that I ‘saved’ are nearly half an inch wide (they don’t come cheap). So between us all we can rid the country of this blight and have a enough cable ties to last a lifetime.
If you should find any that are still holding up a sign check the date if its passed I consider it to be litter.
