These punches take the work out of making eyes that really do match. Simply position the punch, push hard while rotating and a perfectly round eye will be made. Further details can be added with a knife or paints. Punches are 4 1/2" long and made from cold-rolled steel and easy to re-sharpen. Use a smaller punch within a larger for the pupil.
