I will tell you the truth, the quality is excellent, with water it does not come off, resistant to sweat, they do not itch, they are easy to remove and the glue does not irritate the skin and this, for those like me who have sensitive skin, is a cola that immediately made me love it. They are also easy to apply! The shipping time is long, but it fits, it doesn't go beyond two weeks. Of all the patches I've used these are my lifesavers!
