i against i
Bluelighter

so i'm new to iv and picked up some of those all in one nevershare steripacks, just curious as to what those paper things on the left are for? i've looked up the kit and they must be the "blood proof pad", for use after the shot? the filter than comes with them is like half a cig filter, should i poke the needle in and draw up, or just rest the bevel on the top?
thanks.
