Where to start! My favourite product! Window Cling!!
It is exactly that. An amazing non-sticky product that literally clings to glass or mirrors, inside or out. It can be used in its single colour, or it can be printed to full colour. It can even be cut into shapes.
It can be applied to the inside of glass so the printed design faces outwards, or with it facing inwards.
And this is all because it is held in place by static cling.
If you are a small business owner do consider this product for seasonal displays if your windows are not tinted. It could make an amazing difference to footfall.
Likewise clubs love making 'badges' for their customers to display in their cars. Interesting fact: it is still legal to display a 12cm diameter sticker in the front passenger side of a car windscreen where the tax disc used to be (if you remember those).
