Review (4/5): They work well
What I liked best about these stencils is that it makes drawing or shading eyebrows much easier than freehand. I also like that you don't have to hold them in place to use them since the adhesive sticks to your skin. It doesn't irritate your skin and is disposable, however, you could get two or three uses out of each pair if you're careful. I would have liked them more if they came in larger shapes as these were for thinner eyebrows but I prefer a fuller and wider brow. over-all these are great for beginners and those with shaky hands.
