Does anyone know if the blades on Amazon.com listed as: "100 Crystal "SUPER +" Platinum Double Edge Safety Razor Blades A.K.A Israeli Personnas" are really Personnas? http://www.amazon.com/Crystal-Plati...sonnas/dp/B002CE3518/ref=cm_cr_pr_product_top I've found that the red Personnas are very forgiving on my face, but I don't know if these are really equivalent. I see that West Coast Shaving has the red Personnas, so I might order through them to be safe. I got most of my shaving gear from them to start with, and they have been very helpful.
