Sinterklaas is a Dutch tradition of giving presents to children at December 5th, the anniversary of St. Nicholas. When the kids get older this is often replaced by exchanging surprise presents. In our house the tradition grew that I make all the presents.
Here are 2 out of 4: the present for my son Mart. He recently bought a motorscooter and a bowl with black fish. The other is the present for my wife, Gertie. She has some health issues with her hands, called the "Carpaal tunnel syndrome". Also known as "sleeping hands".
