There was a noticeable difference. So I have the packages placed on the scale with the following result:
Old lighter pack of 2 Years = 1 pack 184g
New package arrived today = 1 pack 140g
The number of lighter has remained the same, but there were material loss to 40g, which is almost 25% less for the same price. A lever to maximize profits has thus been drawn in the last two years.
Let's see how represent the lighter in everyday use, if there are variations here, I'll look around for new Kaminanzündern.
