I read on another thread that someone uses foam pipe insulation cut to length to ship eggs. They bought it in different diameters so they could get the best fit for individual eggs.
Mine came in bubble wrap envelopes that were about 4 inches square with a flap. They were laid flat in the box for shipping.
