Chocolates, hidden in plain sight

My team won a box of chocolates for coming second at the local pub quiz.  I've placed the box in plain view for anyone to see in our hall.  I've challenged the children to find it, in 2 weeks no-one has found it yet!  Even the wife didn't see it for a while, until I pointed it out to her.  I suspect she's been sneaking the occasional sweet on her way past so there might not be any left when a small child eventually finds it.

Can you spot it?
