The claims below are in addition to those above.
All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A temporary facial tattoo for application to a users face, the tattoo comprising:
a) a substrate layer formed of a substantially planar sheet of water permeable material,
b) a decorative ink layer disposed on one side of said substrate layer;
c) an adhesive layer disposed on a side of said decorative ink layer opposite said substrate layer;
d) a protective covering layer disposed on a side of said adhesive layer opposite said decorative ink layer, said protective covering layer being transparent and removable from said adhesive layer;
e) four apertures extending through each said layer, two of said apertures forming eye holes, one of said apertures forming a mouth hole, and one of said apertures forming a nose hole;
f) said nose hole having two spaced slits extending away from said nose hole forming a flexible nose flap, said slits being spaced apart from each other and extending through each of said layer; and
g) wherein the protective covering layer is removed prior to application to expose the adhesive layer, the tattoo is secured to the face of the user by the adhesive layer, the substrate layer is wetted to release the substrate layer from the decorative ink layer, and the substrate layer is peeled from said decorative ink layer exposing the decorative ink layer on the face of the user.
2. The temporary facial tattoo recited in claim 1, wherein said facial tattoo is cut with scissors to provide custom sizing and shaping for the face of the user.
3. The temporary facial tattoo recited in claim 1, wherein said tattoo is available in a plurality of sizes.
4. A method of applying a temporary facial tattoo to the face of a user, the method comprising:
providing a temporary facial tattoo, the tattoo comprising:
a) a substrate layer formed of a substantially planar sheet of water permeable material,
b) a decorative ink layer disposed on one side of said substrate layer;
c) an adhesive layer disposed on a side of said decorative ink layer opposite said substrate layer;
d) a protective covering layer disposed on a side of said adhesive layer opposite said decorative ink layer, said protective covering layer being transparent and removable from said adhesive layer; and
e) four apertures extending through each said layer, two of said apertures forming eye holes, one of said apertures forming a mouth hole, and one of said apertures forming a nose hole;
f) said nose hole having two spaced slits extending away from said nose hole forming a flexible nose flap, said slits being spaced apart from each other and extending through each of said layer;
removing the protective covering layer to expose the adhesive layer;
placing the tattoo with the adhesive layer against the face of the user;
pressing the tattoo against the face of the user;
wetting the substrate layer with water to release the ink layer from the substrate layer; and
removing the substrate layer from the ink layer exposing the ink layer on the face of the user.
5. The method of applying a temporary facial tattoo recited in claim 4, where the face of the user is washed and dried prior to application of the tattoo.
6. The method of applying a temporary facial tattoo recited in claim 4, wherein said tattoo is removed from the users face with a cleanser taken from the group consisting of soap, water, baby oil, and transparent tape.
7. The method of applying a temporary facial tattoo recited in claim 4, wherein the user aligns said apertures with corresponding facial areas to ensure accurate placement of the tattoo.
8. The method of applying a temporary facial tattoo recited in claim 4, wherein an applicator infused with water is used to wet the substrate layer.
