Does Cussons Pearl soap still come in a box like that?

Sadly not. It's now a very Tampaxy shade of blue. I loved that soap box when I was little though, it was the prettiest thing ever.

"I guess I'm just a bit surprised that someone who couldnt remember the name would ask what the name of those crappy coated crystals are rather than asking what the northern lights are called.
