Everybody loves stickers! Give a sticker away and does the person just throw that sticker in the bin, like they would a leaflet? No way! They are compelled by the laws of nature to peel the backing off and stick it to something.
Think about how many people will see that sticker now. How many stickers you have on your stuff. There’s your laptop, phone, gadgets, notepads, desk and an endless list of surfaces you can brand up. Make your brand sticky.
