works but not sure about a whole day [SEP] i think i like these but i am not sure how long they will stay on especially if it is warm out i used them for a video i made i do youtube videos and i hate the way my neck looks they make a big difference but i think they might have a tendency to pop off make sure you put alcohol or something on your neck so there is no oiliness it is a good idea for short term use i think but i am not sure about a whole day
