Anyone else tried this?

A friend of mine from the U.K. gave me a jar of famous “Jelly Babies.”  Americans have probably never heard of them, but they are essentially fruit flavored glycerin candy, in the shape of little babies.

What I don’t understand: the container is made of a heavy, nearly indestructable plastic. Why?  Are jelly babies so dangerous they need to be imprisoned in thick plastic? Are they so sensitive they need to be protected?

Anyway, it seemed to me the container would make an ideal piggy bank:

However, the only way for me to cut a slot into the hard plastic was using my high speed abrasive grinder!

The central question remains: why would Brits over-engineer something like this?
