stainless coffee cup with lid

Common capacities range from about 16 ounces up to 40 ounces, with many options clustered around 16–20 ounces.

Many models include carrying or ergonomic handles, and several list cup‑holder compatibility to make on‑the‑go use easier.

Some mugs include removable stoppers or straw assemblies and come with extras like plastic straws or removable lids to simplify cleaning and drinking.

Warranty coverage varies by brand and listing; common examples shown include lifetime limited warranties, 5‑year limited warranties, and 1‑year limited warranties.

Most listings simply state stainless steel as the material; several product descriptions specifically note food‑grade 18/8 stainless steel.

Care instructions vary: some listings recommend hand‑washing the mug body while noting that lids or parts are dishwasher‑safe; other listings mark the mug or specific parts as dishwasher‑safe.

Many lids are described as leak‑proof when closed. Other common features include safety locks, slider or snap closures that seal when shut, and splash‑proof designs.

Most use double‑wall, vacuum insulation. A few product descriptions also mention a copper‑coated layer on the inner wall for additional insulation.
