I recommend the Innisfree eyelash curler.

This is the Innisfree eyelash curler with a curvature most suitable for the typical Korean eye shape.

I've been using this for several years, and it always lifts my eyelashes to the fullest.

It is also highly durable and rarely breaks down.

You just need to replace the rubber tip. Three refills cost 1,000 won. I highly recommend the Innisfree eyelash curler.
