Listings show three primary materials: standard glass, lead-free crystal, and a titanium crystal material.
Common pack sizes across listings are 2-piece, 4-piece, and 10-piece sets.
Most options are clear/crystal or lead-free crystal; at least one tumbler is offered with a deep amber finish as a color variation.
Some stemmed square glasses are shaped—with square bowls and specific rim designs—to promote effervescence and enhance aromatics. These design features are called out for sparkling wines like champagne and prosecco.
Styles include stemmed square glasses (champagne and wine shapes), short tumblers/whisky-style tumblers, tall long‑drink/highball tumblers, and square shot glasses. Some tumblers also feature decorative cut patterns such as Cross, Diamond, Square, and Straight.
