I forgot to mention, its kindda gross looking, it is black and like a "Thick"onitment. It reminds me of tar. I have gotten it at the local pharmacy, no prescription needed but had to ask at the counter for it. It has always worked well for me.
My son had a deep splinter I put this on over night and the next day it was much easier getting the rest of that splinter out of his little finger.
Good luck with it :)
