Top of the line mirror glass.
This is a premier product of the stage magic "Mirrored Glass".
This is a glass type product.
The new design has a vertical line that makes it difficult to tell the existence of the mirror than the previous one.
The vertical line is also strong at angles and makes it easier to play.
Although it is made of glass, the legs are thicker so you dont have to worry about cracking.
As an example of performance...
Pour wine into the wine glass.
You can turn the glass over over to make a mistake, but the wine will never spill at all.
No...
Wine has changed into silk.
