Review title is Great concept, however..... [SEP] There are a lot of these type products out there, but these seemed to best and the most complete set of stencils.  However, unless you have a small head, you will have to create your own elastic band to hold them on.  If your head is average or large, forget it, because it stretches the stencil so much that it causes the eyebrow templates to pull open and then you have an extra wide and distorted template.  To me, these problems could be solved by enclosing an adjustable elastic band and making the templates just a little thicker so the template can keep it's integrity.  There seems to be quite a good array of templates and there was one that matched my eyebrows, but once I put it on, it was very distorted and without the elastic, it is difficult to just hold onto while trying to use it.  Too bad because it could be a great time saver when doing eyebrows.
