(From a package of DORCO brand razors I bought the other day)

The features of Dorco “DORCO”

By adopting micro grinding method which is far different from the existing grinding methods, Dorco “DORCO” could have the edge of curve and tooth shape that assures comfortable feeling while shaving and long durability.

The lubricant oozing out from the lubricating strip attached to the top cap of Dorco “DORCO” reduces friction between the razor and skin and prevents skin damage while shaving.

Two blades are positioned in such a way that the first blade stretches your whisker out as it shaves the whisker and then the second blade shaves the remaining portion of the whisker for a perfect shave.
