The stickers have only been on the hearing aids for fifteen minutes, so I can't say anything yet about how long they will stay in place and remain beautiful.
I can say that the service provided by Michiel and Tiny is really very good. Michiel personally contacted me after I asked which model I should choose because I didn't see mine. Even after everything had been arranged, he asked if the order had arrived correctly.
And not entirely unimportant... it is difficult to choose not only for children but also for colorful adults like me with so many different fun stickers!
