they work well [SEP] what i liked best about these stencils is that it makes drawing or shading eyebrows much easier than freehand i also like that you do not have to hold them in place to use them since the adhesive sticks to your skin it does not irritate your skin and is disposable however you could get two or three uses out of each pair if you are 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
