I find the claims that P&G makes to be interesting, because unless something has changed, Dollar Shave Club does not actually produce or manufacture under license any of its own products, rather the service is about the delivery and cost mechanism, not the actual product received. Instead, they use products made by Dorco, a South Korean company, <a href="http://www.dorcousa.com/" rel="nofollow">http://www.dorcousa.com/</a>.<p>The 4X, for instance is the same as the Dorco Pace 4 blade system, including compatibility between the cartridges/handles. I think Dollar Shave Club may provide unique handles, but the razor blade cartridges themselves are made by Dorco.
