Email Diamant. What is it? What can it do for you? (And since when does a matador have anything to do with emailing?)
Now that you've guessed away, I'll answer your questions and put you back at ease. "Diamant" translates to "diamond". "Email" translates to "enamel". And so the name of the mystery substance is "Diamond Enamel". That's right... toothpaste!
I can't begin to explain the matador.
