Rapira Swedish Supersteel blades get really good reviews. These are actually made in Russia. I recommend these blades for someone who is comfortable with using a double-edge safety razor. I always recommend starting with the Astra blades and then trying a different blade. Most users will get at least 4 shaves out of a single blade. Everyone has their own preferences.
Each package comes with 5 blades.
***If you travel by air- these blades are NOT permitted in carry-on bags.
