Customizing possessions, unheard of before the 18th century, grew popular after Mozart painstakingly sewed sequins onto his composer cape in the shape of a fire-laced treble clef. Continue the pursuit of self-expression with today’s Groupon for hand-painted glassware from Classy Yet Sassy. Choose from three options:

• For $13, you get two custom-painted champagne flutes (a $26 value).
• For $18, you get two custom-painted goblet or red-wine glasses (a $36 value).
• For $18, you get two custom-painted pub glasses or beer mugs (a $36 value).

The glass-gilding artisans at Classy Yet Sassy artfully embellish glassware with hand-painted custom designs that celebrate everything from anniversaries to beloved sports teams. Workaday drinking vessels transform into chalices commemorating your college graduation or favorite bus ride, realized with a flick of a brush and a dash of whimsy. Crude vitreous subjects are reborn as one-of-a-kind works of art as precious as a snowflake forged from goblin gold. All Classy Yet Sassy glassware is top-rack dishwasher safe, but placing hand-painted glasses in the bottom rack results in jealous outbursts among unadorned flatware.
