Extra close shaves for the smoothest skin. This superior platinum, double edge blades by Astra are the "cutting edge" of shaving products. You get 5 superior platinum double edge blades, which fit snugly in your razor, giving you the closet shave and smoothest skin time and time again. The added benefit of the traditional safety razor is the gap between the blade and the frame, allowing hairs to escape the head of the razor, rather than getting stuck like disposable heads. Another great thing is, these razor blades fit on any safety razor.
Green vs. Blue
The only main difference is their sharpness. Razor blades are defined in sharpness from 1 to 5. Type 4 is for light to heavy hair thickness and growth. Type 5 is great for more advanced users and for light to very heavy thick hair.
- Green is type 4 sharpness
- Blue is type 5 sharpness (most sharp type ever)
