Taxidermy & Tanning Assistant
Chemical pickling, tanning agents, glass eyes, and form fitting.
Ocular Measurements
Estimated Glass Eye Options
The horizontal pupil must remain perfectly parallel with the ground level of the mounted pose.
Positioning glass eyes correctly in mammalian species is paramount to avoid giving the mount an unnatural, blank, or startled appearance.
