The ornamental design for a eggpen, as shown and described.
FIG. 1 is a side perspective view of the egg pen, showing my new design;
FIG. 2 is a top view thereof;
FIG. 3 is a bottom view thereof;
FIG. 4 is a side perspective view with the pen shown separately for ease of illustration; and,
FIG. 5 is a top view thereof, with the pen not shown for ease of illustration.
The design consists partly of hair-like bristles. Inconsistencies between the way the bristles appear in the different views are understood to be caused by the variations in the organic material of the bristles, and to the different viewpoints from which the claimed design is shown.
