OK, I have some other magnetic eyelashes which do not utilize the magnetic eyeliner, but just use little magnets on 2 sets of lashesthat you sandwich your real lashes between-- they are OK but take me like 30 minutes to get set right. THESE snap right on! And they stay. This was the best idea ever! If you can put on a thick layer of eyeliner (or two thin ones) these lashes will just smack right onto it and hold until you take them off. These are so nice, because you don't have to wash off mascara when you come home tired at night and don't feel like doing it. I love them I just hope the eyeliner bottles will last a long time, or that I can buy extra when it's gone.
