12 blades, as saying it was worth a good time with this package! The XL Pack is obviously more advantageous price level that small formats. These blades fit all the Gillette Fusion razors. I am usually skeptical of 5 razors blades, but this time I must say that I feel a real shaving comfort with them. The result is as polished as with my usual 3 Mach3 blades, which I did not complain. Nevertheless Fusion blades offer a smoother shave, it feels immediately. The tighter blades also make it more difficult to carve, very good point. In short, I am very satisfied with these blades.
