Description of the Related Art

In general, cosmetics that are used for makeup are usually liquid, solid, and a mixture of liquid and solid. Brushes having various shapes or sizes have been developed and used to put solid-state cosmetics on a face.

That is, such brushes are configured to put a cosmetic made of a solid powder on the brush part thereof and appropriately apply the cosmetic on a face, etc. Such brushes are composed of a grip that a user can hold with a hand and a brush part made of a plurality of hairs and formed at the end of the grip.

Various brushes are kept in pouches for makeup and are exposed to the outside without a specific cover for protecting the brush, so the brushes are contaminated.

If a cap such as a case is used to sanitarily keep a brush, the volume increases, so it is inconvenient to carry the brush. Further, it is required to separate the case every time to use the brush and the brush and the case are separate while the brush is used, so there is a possibility of loss of the case. Accordingly, measures for removing this problem are required.

The above description is the background for helping understand the present disclosure and does not means the related art well known in the art.
