Straight razor with a "guard"
That's basically what this is.  First off, the box is written in Chinese, I believe, with absolutely no English on it.  No instructions other than a pair of pictures.  Not great pictures either.  Not to be deterred, I opened the box, pulled one of the razors from the box, removed the plastic cover and tried it.  If you look closely at the one picture, you will see what appears to be a drop of blood - it is.  That is why I described this as a straight razor with a guard in quotes.  Make NO mistake, these are SHARP.  Use them delicately and only on smooth skin.  If you have a blemish, a mole or anything just slightly raised on your skin, it will be cut off.  You will bleed.  Just want others to be aware of what this is and to take care not to hurt themselves.
