How about chocolates with a Turnhout link? These are small tasty delights with views of the city such as the castle of the dukes of Brabant, the Wetlands, St. Peter's Church, the Taxandria Museum, the Beguinage and the playing cards. You have them in milk chocolate.
Do you want to keep these for yourself or to give as a present to someone else? You can find boxes with twelve chocolates at Toerisme & UiT. For the milk chocolate you pay eight euros per box.
