Organic Cotton No-Show Thong

I purchased these in black and there is no way the black dye is organic or natural in any way shape or form they reeked of a strong “sharpie” or marker like chemical (obviously I know it’s not made from that but still super bad for underwear, I’m not putting that near my private parts if it smells of pure chemicals, I didn’t even try to wash these or take tags off because they are being returned for sure! they are also 80% cotton not 100% . organic cotton companies need to do better. This is greenwashing to the max!
