Nail serum I bought with my own money

This is a nail nourishment I bought at Daiso. Since it's called a nourishment, I bought it expecting it to absorb rather than coat like nail polish, but it actually coats the nails with a slight shine, just like a base coat. It applies very thinly and has a subtle gloss, so it isn't overwhelming. I think it could even be used as a substitute for a base coat. It seems like it can be used for multiple purposes—as a nourishment, a base coat, and for neat nails.
