Simply swipe only on the parts you want! It's convenient.

I am using this eyelash curler. There are some lashes that are hard to curl, but if I curl them once with this, they curl up perfectly. It is small and convenient to carry around, and it is a good product in terms of value for money. At first, it curled my eyelids too and was a bit difficult, but now that I’m used to it, it curls them up smoothly in one go.

If you have sparse or thin eyelashes, a partial curler will be useful. I tried it once and found it convenient.
