Fluted cups are made from a range of materials, including stoneware, borosilicate and regular glass, various plastics (such as polystyrene), and stainless steel.
Some fluted tumblers include a wooden lid with a hole for a straw; the lid helps keep drinks fresh and supports on‑the‑go sipping.
Listings show fluted cups used for champagne and mimosas, a variety of cold beverages, and—when in stoneware—hot drinks such as coffee, tea, and cocoa.
Some fluted options use double‑walled construction or heat‑resistant borosilicate glass to help keep drinks hot or cold longer and reduce condensation; one stainless‑steel variety also notes an internal ceramic coating to preserve flavor.
Capacities shown range from about 4.3–5 ounces for champagne‑style flutes, to around 9 ounces for some stemless insulated flutes, 14 ounces for fluted mugs, and about 21 ounces for fluted tumblers with lids.
Common details include fluted (ribbed) sides, thumb‑rest handles on mugs, double‑walled or faceted silhouettes on insulated stemless pieces, and some glass tumblers that add wooden lids or small decorative motifs.
