Thanks!! These remind me of tea bags, and the big white things behind them in the picture are sticky pads. You put the little bag on the bottom of your foot and put the sticky pad over them to hold them on! Then you keep them on over night. I had got them and never got to try them, I had cancer on the bottom of my foot years ago and where my skin graph is I was afraid to put the sticky pad on it! So I thought I would share with someone who could use them! So good luck if you bid =0)
