It's the Etude eyelash curler!

This is the Lash Perm Curl Fix Eyelash Curler. They say it maximizes the curling power of mascara. It comes with two refills, so it lasts a long time. To curl, simply press the curler about three times from the inner corner to the outer corner, following the curve of the curler. They say it works best if you curl in stages. It works well with Etude House mascara. It is on sale for around 5,600 won at the official store, so I recommend buying it along with other items you need! I'll be learning a lot from Unpa^^
