Good quality but the glue is not it
"First bought the period patches years ago, helped subside cramps a little so thought I’d give these ago too. Good product, I think I notice when I don’t use them compared to when I do … however, I don’t have sensitive skin or allergies and the new backing glue is not great tbh. Really difficult to peel off and leaves a red ring on my body where the patch was that stays for days, the old ones did not do this … please investigate!"
