This is a blade that is available worldwide, originally from Korea, they have been producing razor blades and related products since 1955. As with most consumables, some will love them, some will hate them. Being one of the cheapest options out there, it is certainly worth a bash for consumers on a budget.
Over time these have proved to be very popular in our store, so there is a good chance you will find them perfectly good. The latest version seem to have been upgraded, I am looking forward to getting feedback from regular Dorco users, are they better or much the same?
