convenient [SEP] update so i have applied it this weekend and it does stay on for a couple hours but does not last all day and with that being said i highly doubt it is waterproof it was not on long enough for me to try it i have tried different stencils and the shapes suck i gave stars instead of one because it still is better than just using a brush but still have to fix the end with a brush it is very convenient but the shape of the stencils sucked none of them have an actual pointy end they are all rounded i only tried one brow but i will updated after the weekend to see if the waterproof part actually works
