In March 2014 DSM Keukens opened up a new shop in Ostend. To put this opening well into the limelight DSM Keukens decided to be present in the letter boxes of their potential customers in the run-up to it.
With a folder in the seal package and a sticker on top of it, DSM Keukens managed to get more people to their opening. The extra visibility of the sticker-on-seal represented a great tangible contribution to the success of the campaign.
