these will hold on [SEP] i have been experimenting with glue free and magnetic free lashes and i really enjoyed using this product is it my absolute favorite at the time of writing this review so far yesi really like the formula of the eyeliner it has been one of the smoothest i have tried so far as for the strength of the adhesiveness of the eyeliner with the lashes it is super strong even the slightest touch of the lash to the eyeliner will have it stuck the eyeliner also is very water and smudge proofi have only taken one star off because the lash band itself can be a little bit irritating for people with small eyelids monolids while wearing these lashes the inner corner of my eyes were feeling a bit irritated because the band was poking the skin eventually this made my eye water and the inner corners of the eyelash were beginning to peel up i feel that if i readjusted these lashes or cut some portion off it would help with the issue
