As it says in it's title, it's a mirror glass. It's a plastic cup. It says it's almost unbreakable
but I know that if I gave this thing a hard squeeze it would crack. For the price though? Not so
sure you can beat it. It's still a good mirror glass. It should be pointed out that it is in fact
sealed and able to be used with liquids, but does not come with the necessary ingredient to do the
liquid vanishing (if you want to turn the glass upside down, that is). In general, angles on this
are good too. You maybe have 120 degrees if you hold it straight on to audience. All in all, a good
mirror glass - I couldn't find anything better for the price.
