Koji x Dermaroller

Why is Koji's skin so beautiful? Put an end to that question.

In fact, one of the items he continues to use in real life is a dermaroller.

This collaboration started with his wish that "I want everyone to have the one I use on a daily basis.

The specifications of the device are the same as the previous model, but only the specially designed "Koji package version" is available.
