did not come with instructions [SEP] i do not know if these will get much use i do not know how to use them properly for my eyebrows and will have to do some u tubing to find out there are not any instructions included i do know i will not use them on any area other than my eyebrows some women will probably use them on their upper lip and chin area but not me i have always felt like if you shave some areas more hair grows back in this may be a myth but my daughter shaved her belly and her arms and she has hair growth that is darker than what she had previously she did this for a few years and has since stopped but the hairs on her torso are now an embarrassment for her
