Does not stamp on eggs
An egg is rounded and larger at one end than at the other.  There is no place to stamp a flat stamp.  They did say it was a "flat" stamp but they also showed a picture of it beautifully stamped on an egg.  I tried everything and no way did I get more than part of the stamp on an egg.  The egg would have to be huge (like an ostrich egg, lol).  The stamp is cute and works well on paper or on an egg carton, so there are uses for it.
