Possibly the closest shave I have gotten next to the feather blades. These blades feel abnormally thin next to other blades. They come in a cardboard box, no dispose unit attached.
They are double sealed in an outter coat and an inner coat of wax paper. They have a thin one coat seal on the outside of the blade. I got about 5 shaves out of it before I felt a reduction in sharpness. Very smooth shave and awesome around the neck and chin. Very sharp, very affordable. Great blade for a beginner to start out on because you can really feel the cutting edge.
