Electronic book store "Four Directions" is an environmentally friendly business. Naturally, the book store was looking for ways to advertise offline that wouldn't be harmful to the environment. Rather than using printed flyers to distribute a QR code, Grey Hong Kong invented an environmentally friendly advertising medium with only HKD40,000 budget- QR cookies.
