미띨이야
손 발톱이 약했는데 써 봐야겠어요
This is Kerasal Nail.
This product strengthens split and brittle nails. Although it feels a bit on the expensive side considering the amount, I recommend it because I feel my nails becoming stronger after using it.
I've noticed that people with toenail fungus apply it too.
It's adorably small, so it's convenient to carry around when traveling.
