The blades of the 12er packs do not meet the standard, as found in 4 or 8 packages. Besides the fact that you cut yourself, wear these blades much faster. Amazon have noted, unfortunately came back not much. You will pass the complaint and contact me. I can return the item yes. After the blades were already used, etc. this option turned out, of course. To this day (almost 2 months later) no one has contacted me. Super Amazon, thank you!
