I bought these for 3gp on my way to Qeynos from Erudin. :) I promptly gave them to a monk in Erud's crossing who was panicking and running from wisps. (After I killed the wisps on him.. poor kid.) He found out the HARD way you need magic items for your hands and feet. I directed him towards the warrens, where bigger promise of exp and possibly some better gear awaited. He thanked me much, and we both went on our way.
(And if you must know, yes, the boat stops at Erud's crossing coming FROM Qeynos.. I had gone AFK -_- had to ride the boat twice.)
Best 3gp I ever spent. I never saw a pair of these drop while hunting in Warrens.. but I know they do drop. Just not as often as the anklewraps on my server :)
PS ~ *psssst* .. the look is leather, folks :)
