I recommend the Shiseido eyelash curler! I've used so many curlers that I must have thrown away dozens of different types, but this Shiseido one has established itself as my holy grail!! It curls your lashes smoothly, and the staying power seems good too! Of course, you should use a good mascara as well for double the results.
It’s effective, but you know how frustrating it is when your lashes fall out while you’re clipping them? This one really goes on without any of that happening!! I recommend it.
