  • Publication number: 20210000242
    Abstract: A mascara comb allows a user to quickly apply mascara liquid to the eyelashes without forming clumps. On the upper surface of the mascara comb a plurality of protrusion elements are disposed so as to form a plurality of rhombus structures; the rhombus structures are configured so as to form a predetermined gap for applying the mascara liquid to the eyelashes while combing the eyelashes, wherein a diagonal line in the axial direction of the comb portion forms a rhombus longer than a diagonal line in the orthogonal direction orthogonal thereto; further, the rhombus structures function as a velocity adjustment mechanism for making the velocity with which the mascara liquid flows in the axial direction slower than the velocity with which the mascara liquid flows in the orthogonal direction; and the inside of the rhombus structures are a holding portion having a function of holding the mascara liquid.
