The Verdict. Color me impressed—I definitely think magnetic liner is the real deal. Application is super easy, the lashes stay on all day, and no-lash-glue-required also means no more picking leftover clumps of the stuff out of your real lashes (or washing the gunk on your falsies before reusing them).

Do magnetic eyeliner lashes stay on?

They will actually last for as long as you take care of them as there is no glue to clump up on the lash band, contorting and messing up the lash, which makes normal lashes unusable after a few uses. The lash and eyeliner hold up to 10 hours (essentially, the entire day).

Does magnetic eyeliner ruin your eyelashes?

The lashes that come with magnetic liner adhere to the the eyeliner, which is on the eyelid skin. Therefore, it shouldn't cause lash loss unless you have an allergic reaction to the liner or lashes themselves.
