I recently ordered a carton(200) of my beloved Red Personnas from Shaving.ie. They are the white plastic packs of 10 as opposed to the red cardboard packs of 5. I have shaved with these many times and know these blades well. And these are not up to snuff. They seem to have the same sharpness but lack the smoothness I have come to expect from these. Could they have changed something? Is this a defective batch? I am very dissapointed with these for the first time.
