glue or magnets [SEP] saw this product so just had to try it i bought the double magnets prior where one set goes behind your lashes and the other set in front and they never really met up properly so i never used them i do not like the glue because it always takes my real lashes off so magnetic liner yes please i did watch some youtube videos prior to buying to see how to put them on properly i put a thin line on first with no luck so i put a thicker much thicker line on and waited a bit before putting my lashes on i am not sure if it is truly magnets that hold them in place or just the goo glue substance of the liner i will say that with magnets you feel a pull sensation where the magnets are drawn together i never got that feeling with this liner so my guess is it is more the goo of the liner that holds them on still better than glue either way i have them on and i hope the goo holds up for the entire day after wearing these eyelashes for a full day they stayed on without any issues be it magnets or goo i am thrilled with using this product again and again
