The edges may be sharp. The amount of shell in each bag about an egg or a little less. The shards do not all come from the same eggs, so there is variety in the pore patterns and shell finish. All were premium quality eggs before they broke, all from domestic Rhea. The label, for scale, is 4 x 3 inches and the bag is 4 inches wide. Length depends on where the label was attached. We have a wide variety of eggshells for mosaic and each listing is different. Contact us if you don't see what you are looking for!
