The cuts on the eggs are nicely made and look "real".
Like all or almost all Chin's puzzles, this one is not super difficult but will still puzzle you a bit of time. And like all his puzzles, the mechanism is not super complicated, but very efficient and well designed!
So far, I have not seen such a "mechanism" implemented in a puzzle and I liked a lot the way of solving it. And it's easy to repeat!
This is an egg(cellent) puzzle :)
