The ornamental design for a wavyhairpen, as shown and described.
FIG. 1 is a perspective view of a wavy hair pen, embodying my new design;
FIG. 2 is a top plan view thereof;
FIG. 3 is a bottom plan view thereof;
FIG. 4 is a left side view thereof, the right side view of the handle portion being a mirror image thereof, the only difference being in the upper portion in the disposition of the strands of wavy hair;
FIG. 5 is a rear view thereof; and,
FIG. 6 is a front view thereof.
The variability in the disposition of the wavy, hair-like strands shown in the drawings is due to the nature of the hair itself, and is not illustrative of deliberate differences in design structure.
