Eyelash curling product recommendations

I wanted to buy eyelash tweezers, but when I went to Olive Young, there were so many types that I couldn't choose one.

Sometimes, while trying, I even get pinched in the eye and tears stream down my face. Everyone around me seems to do it so well; I don't know if it's my lack of skill or my equipment, but I fail every time.

If you know of any good products, please share them.
