rub it to heat it before applying [SEP] these strips are tricky at you nedd to warm them to get them to stick properly i rubbed my hands on it for a minute to heat it up then pealed it apart and placed it on my legs and was able to remove of hair on the first try i got better as i learned and the warmer it is when you peel apart the better it sticks and the more hair that is removed amazing price this will do a lot of waxing for you
