These are great blades, for beginners. These are great blades for seasoned wet-shavers as well. Astra is a Russian subsidiary of Gillette, which is a component of Proctor and Gamble. It's nice to see P&G still making DE razor blades.
These blades give a really clean shave, and, they're not a very fast action blade, either. What I mean by that, is, you're not likely to 'over stroke' and, cut too much. They're not as slick as some other blades. I don't like blades are that are super slick, but, these might be a tad too far in the other direction.
Overall, this is a really great blade. They're not as sharp, or, aggressive as some of the other brands, which makes it great for beginners, or, those looking for the exact blade to fill their niche.
