Liked this product because it is pure and goes on smoothly. After shaving with it for several days, it actually pulls 'impurities' out of the skin in the form of little 'pimples' that go away leaving no dark marks on the skin with continued use.

Great post shave treatment. You will use this stuff and love it. I'm almost through my first block of it and it has been about 18 months (but I don't shave everyday). Just buy it.

Store this on a soap-saver and it will last you years and years. We've used ours for a couple of months and it still looks brand new. This truly tones down razor burn and keeps skin from that ruddiness of shaving.

This product is fantastic to use after a shave. You simply wet your face and rub the Alum where you shaved. This will cause any small nicks or cuts to clot and seal up. Unlike Stypic, you won't be left with chalk-like marks on your face. It stings a little bit, but I believe it has antibacterial properties which are helpful to keep away razor burn.

I have to say that despite trepidations of ordering online, my transaction with Oso Grande was absolutely flawless. I emailed Oso Grande about a knife availability and promptly got a response within hours. I proceeded to call and place my order over the phone. A follow up "thank you" email and tracking email was sent to me straight away and the knife, a Spyderco Delica 4 Titanium/Damascus showed up perfectly. Overall, I would be happy to recommend and order from Oso Grande again.
