Olive Young King Hair Roller

If you have long hair with side bangs, here is the convenient Olive Young extra-large (diameter 5.8 cm, length 12 cm) hair roller!

It's also great for adding volume to a large amount of hair at once.

I find these rollers very useful when I want to add some volume to my hair during the rainy season; I curl my hair with them and blow-dry it, and it makes it feel a bit fuller.
