New - 3- Medi Medical Compression Knee Highs. Comfortable, uncoated spandex, proven to improve blood flow and positively affect the symptoms commonly associated with vein disease. The 30-40 mmHg is a firm medical compression for severe varicose veins, post sclerotherapy and prevention of post-thrombotic syndrome.
One box has been opened for someone to look at. The knee highs were not used. I ordered a size large and it should have been a medium.
