Women are applying nail polish on the surface of their nails for nail beauty. However, the application of the manicure is very cumbersome and it takes some time until the manicure is hardened, so it is difficult to go out quickly. In addition, the nail polish applied directly to the nails can be dull and quickly tired, which is why it is difficult to remove the nail polish with acetone and then apply a different color nail polish. There is also an economic burden because it is necessary to have a variety of manicures of different colors. In addition, it is not easy to vary the shape of the nail itself, and frequent repetition of applying nail polish directly to the nail and erasing it with acetone may adversely affect the health of the nail itself.

Therefore, in order to alleviate this hassle and to produce beautiful nail shapes while maintaining the health of nails, artificial nails by injection molding have recently been developed. This artificial nail is made to adhere to the surface of the nail with an adhesive such as a double-sided tape. Since the surface of the artificial nail is a resin color, in order to use it, a manicure of a desired color is applied to the surface of the artificial nail in advance, and it is selected and used as necessary.
