Regina – The World’s First Branded Coffee Stain
Regina, Europe leader in kitchen towels, wanted to promote their brand to key account holders in Germany.
So they used a mug with a new design, that when you let the coffee spill, you can see the Regina logo in the table. To clean the coffee stains they used, off course, Regina kitchen towels.
This action was very successful for the brand, and the people loved so much the idea that they even take home 36 mugs :p
