(4) Therefore, the spherical surface shape of the pressing portion 10 allows for the creation of a marbled pattern resembling an eye, while the surface shape of the constricted portion 14 of the grip portion 12 allows for the creation of a complex gradation pattern resembling the letter "X." In this case, as shown in the reference front view showing another example of a pattern, if different layers are used, the visible area of ​​each layer may change, but this does not deviate from the scope of protection sought.

(6) After the rigid core 18 is inserted, a resin lid 20 made of the same resin as the elastic resin on the surface is embedded in the bottom 16 to flatten the surface. (7) Therefore, the surrounding resin layers and the resin lid 20 can each create a well-ordered layered pattern on the bottom 16 side. (8) In this way, by having features 1 to 3, various complex patterns can be formed due to the surface shape, significantly enhancing the design of the entire surface.
