손에도 안묻고 너무 좋은 케이스네요
It's a nail essence pen with the long name, Nature Republic Color & Nature Nail Care Nail Essence Pen!! lol
Since it is a pen type, it is highly portable, making it convenient to carry in a bag or pouch and take out to apply whenever needed. If you twist the opposite end of the brush, the essence rises to the brush, and once it has soaked in just the right amount, simply apply it directly to your nails. It is so convenient!
If you apply it to the areas around your nails along with your nails, it helps to smooth out the white hangnails and cuticles, keeping the area around your nails neat. I also like that it doesn't feel slippery after the essence is absorbed.
I tend to forget to apply bottled nail essence, and it's a hassle to carry around, so for a lazy person like me, I think pen-type nail essence is the easiest to use.
