These glasses would be excellent to have at your next dinner party, wouldn’t they? The graphics are musical notations for the correct level of liquid to produce the perfect pitch when a user runs their finger along the rim of the glass. As the price is for a set of 2, you’ll need to shell out a fair amount of dough to get a complete octave.
Comes as a set of two.
Also available directly from Luna & Curious for £23.50.
