I use a clip has shaved ruby since 2012 (recommended by the make-up school where I was), I bought it this year and I am fully satisfied as to my old .... I have never found such a specific clip, which is great for the eyebrow in order to have a perfect result.
I highly recommend this purchase for people who regularly or pluck pluck eyebrows. for those who want to remove hair by a hair here and there, but why not the price you definitely seem high and not cost-effective compared to your more quoccasionnel use.
