Shiseido eyelash curler

This is a Shiseido eyelash curler that so many people use. I think I bought it a few years ago; it hasn't broken down, and since I only have to replace the rubber, I've been using it for a long time. However, even though it is very famous, the curvature doesn't fit my eyes, so I don't really see any benefits to it. Since my eyelashes are straight, it doesn't seem to curl them very well, and perhaps because I only use it occasionally, my skills aren't improving. I think I need to get a heated curler.
