The tastiest Kitkat variety for fans of dark chocolate (50% cocoa)

The Kitkat bars consist of a wafer, which is wrapped in chocolate. They are similar to Duplo's Ferrero. There are many different versions, with some variations be made for example for the other countries. Unfortunately, this dark chocolate is no longer to obtain (50% cocoa) in the retail sector. I have discovered only at Amazon, in other wholesale markets or abroad pack of 24. That's a shame, because the normal variant with 30% cocoa version I find very sweet and therefore this is my favorite flavor.
