insulated wine cup

Typical capacities include 12 ounces, and some freezer-style stemless cups are offered at about 8.5 ounces.

Common materials are stainless steel for double-wall or vacuum-insulated tumblers and BPA-free plastic for freezer-style, double-walled cooling cups.

Duration depends on construction: gel-based freezer cups are described as keeping drinks chilled for about two hours, while vacuum or double-wall stainless steel tumblers are described as maintaining hot or cold temperatures for up to about 12 hours.

Some options are sold as single tumblers (often including a lid), while others are offered as two-piece sets or packs of two cups.

Some lids include a straw hole or are described as accommodating a straw; sealing rubber gaskets and splash-proof lid designs are noted to reduce splashing when drinking through the opening.
