I do love these lashes, they're subtle but effective and look so lovely and very easy to put on. You will need to make sure you have the lola's magnetic eyeliner to be able to put on. When I've tried other cheap magnetic eyelashes, as much as they work, I have sensitive skin and gives me a slight rash- these don't do that.
However, I will say - I don't think you get 30 uses out of them, I think more like 10 uses out of them...
