It is a hair roller.

I bought this to try it out because it seems to hold hair well if I roll it up before bed.

It seems you need to adjust the angle and pressure properly to dry your hair well without it feeling pulled.

The thickness is just right, so I think I can use it well not only on my bangs but also on the ends of my hair.

And it's good because it's sturdy.

There were many products that broke or snapped quickly, but it seems like this product will last a long time.
