These are some of the nicer nose strips I've tried. I use them from every week to just once a month depending on how many blackheads I develop. After taking one off I can clearly see the blackheads that it has removed. They also don't dry my nose out like some nose strips I've used. The only con I've found is that they smell bad to me. I gave my sister one to try though and she thought it smelled good so it depends on the person.
