I purchased a pair of Gucci sunglasses that had little loops where you can add a metal long chain so that you may take off your sunglasses and wear them around your neck with the chain.. The chain is brand new. I have never used it. You could make a necklace out of it if you’d like I have one hard case two polishing cloths, one silk navy blue sunglass case holder and a green velvety soft pouch. Thanks for looking.
