16. The life-like anatomic feature of claim 1, wherein said anatomic feature includes at least one dye.

17. The life-like anatomic feature of claim 1, wherein said life-like anatomic feature includes one or more dyes to resemble the coloration of the corresponding anatomic feature.

18. The life-like anatomic feature of claim 1, wherein said life-like anatomic feature includes a coating.

19. The life-like anatomic feature of claim 18, wherein said coating is clear.

20. The life-like anatomic feature of claim 1, wherein said life-like anatomic feature has at least one representative defect.

21. The life-like anatomic feature of claim 1, wherein said life-like anatomic feature comprises a face mask.

22. The face mask of claim 21, wherein said face mask is a complete face.

23. The face mask of claim 21, wherein said face mask has at least one representative skin defect.

24. The face mask of claim 23, wherein said representative skin defect is a wrinkle, a fold, a thin lip, an irregularity of the nose, or an acne scar.

25. The life-like anatomic feature of claim 1, wherein said life-like anatomic feature represents a muscle.

26. The muscle representation of claim 25, wherein said muscle representation a sphincter muscle.
