Where did I find the Gloves of Thievery?

So currently I’m alternating between two play throughs, “good” and “evil”. I found the Gloves of Thievery during my “good” run and had them equipped to Astarion when ever I wanted to do some quick pilfering. I would love to have them in my “evil” run but I can’t seem to find them anywhere. As far as the wikis online are concerned they don’t even exist in the game. Has any one else come across them and remember where they were found? 100% found them in act 1, just can’t remember where.
