[0018] The following will further describe the invention in combination with the drawings and specific embodiments:

[0019] Embodiment 1:

[0020] Please refer to Figure 1-2 , a crystal lipstick according to an embodiment of the present invention includes a lipstick cap and a lipstick base. The lipstick cap includes cover A1, cover B2, and inner cover 3. Cover A1 is snap-connected to cover B2 through a first snap member. A first sliding groove is provided on the outer wall of the inner cover 3, and the inner cover 3 is slidably and embeddedly connected to cover A1 and cover B2 through the first sliding groove. The lipstick base includes a middle beam core 4, an inner bottom 5, bottom A6, and bottom B7. Bottom A6 is snap-connected to bottom B7 through a second snap member. A second sliding groove is provided on the outer wall of the inner bottom 5, and the inner bottom 5 is slidably and embeddedly connected to bottom A6 and bottom B7 through the second sliding groove. The middle beam core 4 is press-fitted and embeddedly connected to the inner bottom 5.

[0021] Through the above solution of the present invention, the outer covers of cover A1, cover B2, bottom A6, and bottom B7 can be separated into products of the same shape but different patterns. By providing a lipstick cap made of a transparent material, users can directly confirm the color of the lipstick through the cap without having to open the cap or even twist out the lipstick, presenting a novel visual effect different from the traditional ones.
