I was so impressed when I used it and my foot fatigue was completely gone the next morning. I'm selling some of the ones I bought in bulk. This is a popular sap sheet that you just stick on the soles of your feet before bed, and you'll feel refreshed the next morning. ・1 set (2 sheets) x 10 sets = a total of 20 sheets ・Individually wrapped for hygiene #FootSoleSapSheet
