Ah....thanks for the clarification. I thought the unseen thing had to do with hiding drugs, etc. But then anything hollow would be illegal to bring in...it didn't make sense to single out the eggs.
That's a HEFTY fine! What if someone doesn't know they are illegal? I wouldn't have known that until after I moved here. I had never HEARD of kinder eggs. And I sent some surprise eggs, different brand, to my best friend for her daughter, thinking they were cute. Never had a problem. I had no idea they weren't allowed.
