These are Franzoni STOP CELL stockings purchased from Peach John. 70 denier Color: Black "STOP CELL" high-performance stockings made in Italy by Franzoni. With a thickness of 70 denier, they have firm compression and heat retention, and are designed specifically for cellulite treatment and beautiful leg support. Graduated compression from the waist to the ankles maintains comfortable support throughout the day. The compression function around the abdomen also provides a tightening effect. Made with LYCRA® 3D for an excellent fit. I believe they are equivalent to a Japanese S-M size, but as they are a foreign brand, I am not sure of the exact details, so please understand. They have been stored for a long time, so the outer bag is open and dirty, but the contents are unopened. Please refrain from purchasing if you are sensitive to such things.
