BS Fine Soft Knee Long Supporter - 2 pieces Product Code: BS0947 FWH I just bought these. The product was revised, but these are the new cotton blend type. They have been opened, but are unused. I only opened them, and I haven't even tried them on. They are long, supporting from the ankle to above the knee. They are not available on Amazon, etc., and I ordered them directly from the manufacturer. The price is, unbelievably, double that of the regular type!! One bag contains one piece, so 2 bags are for both legs. You can use them like leg warmers. I myself am a BS Fine user, and I bought these for my family. I thought it would be better to choose something a little better, but they said, "I don't like the color," so I'm going to buy the regular type again... ToT; So, I'm going to sell these. They warm your legs with the power of far infrared rays. Unlike heat-generating materials, they don't get too hot or cause you to feel chilled from sweat.
