They are little pieces of metal that combust when exposed to oxygen. It becomes a fine powder. If someone throws baking flour at you it won't feel like bullets using vinyl cutter printer. But not all the pieces are that small. Last time I saw someone grind a piece hit me in the eye and he dug it out with his finger. Everything's ok but that sharp piece cut a little notch out from the inside of my eye lid.
