Data shows that parents fear to disappoint their kids when they gift used toys. To promote the used toys of Marktplaats, we had to break that barrier. We did so by sharing the ultimate proof that kids love second hand toys, through a simple and very relatable behavioural insight: Children always want another child's toy. So why not give it to them?<br /> <br /> The result was an integrated campaign made entirely out of authentic footage of real kids playing.
