This is a nail base coat.

This is The Face Shop's Trendy Nails Base Coat.
It is a subtle color, so it is good for daily wear, and it is also great to use as a base before applying gel nails.
I liked using it before gel nails because it helps the nails last longer.
They say it is much better for those who have difficulty managing their nails, as it makes them smooth!
I bought this with my own money and highly recommend it^^
