I bought three styles of 'pressure stockings' before. Those from Mama World and Scroll brand are more recommendable.
Mama World 媽x世界 had discount earlier, $140 buy one get one free. Black color, looks as thin as 絲襪 but much tougher 煙韌. So tough it takes a lot of effort to put on. But really worth it because it 'cures' my 水腫 (腳背&小腿) quite effectively.
爽健 Scroll brand is more opaque in color and thicker than the one above. $135 at 護協 but $180+ at Watxons! Also effective but I find it more comfy to wear Mama World's in hot summer time.
Also bought a Japanese one at Log-xn, too too 煙韌, extremely hard to put on and leave so much 襪印 after removing it. No good!
