Clever packaging

I've recently discovered the wonder of Ritter Sport's packaging. The chocolate comes as a 100g 4x4 square, and to open the wrapper you break it along the 3/4 line under the packaging's seam. This pulls the seam apart and immediately gives you a line of chocolate to eat. Absolutely brilliant.

I was looking for a picture of this, and found out that they came up with this packaging in 1976 which is about 20 years before I expected. What's even better is that the company has for a long time had good environmental policies.

Oh, and the choccy is nice.
