When unpacking the delivery seemed suspect. There were two packs taped together, even with 16 pcs. Contents and once with 4Stk.
The 16er box was apparently somewhere imported because everything up to Mach 3 lettering in Arabic (or what language that was also always) was printed.
The blister itself, where the blade stuck all looked completely identical. So I thought nothing more of me.
The horror came the first attempt shaving - razor make it with flying colors, individually pluck all the hairs neatly. The blades totally blunt. For the ton. Even a 10x already used Gilette Fusion achieved better results here and feels more comfortable than the supposedly "new" razor blades.
The only 4 blades were sharp, are those of the 4 single package that was glued.
