Review (1/5): Seemed like a good idea at the time.
I loved the super-thin brush to create an ultra-fine line. but it's not enough to keep the entire lash attached. Even the smallest ones are too large and applying several coats just results in a thick, messy tacky line. I have hooded lids and it transferred the upper lid in the blink of an eye. The eyeliner itself is nearly impossible to remove. I applied it on my hand and had to use a stiff scrub brush in order to remove it.
I tried a few sets of magnetic lashes and only one performed fairly well, but this wasn't one of them.
