Personna Red’s vs the Personna blue white package with red lettering. Honestly, there is no way these are the same blades. I tossed the blades in the blue white package with the red letters. These blades are inferior to the Personna Red package which also wraps the blade in a red wrapper. If you have not tried the real Personna Reds, then you owe it to yourself to try them. To me they are very similar to a Astra SP, but your mileage may differ. Here is a photo of the blades 6ou need to be trying. Embrace the Red’s
