I have been using these blades. For years now. This seller had the best price. So, I will keep purchasing from him. Here's a hack. For men and women who shave and want to get a cleaner shave. I do not use shaving cream or soap; instead. I use a cream like Ponds cold cream or any other soft cream. You will find that the blade slides over much more easily, and you get a cleaner shave. Just rinse the blade under hot water, and the blade will even last longer.
