Most items are made from stoneware. A few listings note ceramic bodies with additional metal or plastic components (for example, stainless steel and polycarbonate).
Available capacities include 10 fl oz, 15 fl oz, and 16 fl oz. Reviewers also mention some related smaller options of about 8 fl oz.
They offer adjustable temperature settings via an app or Bluetooth, a rechargeable battery that keeps drinks warm for about 1.5 hours, an LED indicator, and a smart charging coaster that maintains a chosen temperature (listed range 120°F–145°F).
Heights in this selection range from about 2.95 inches to 4.2 inches; widths run roughly 3.75 inches to 5.43 inches.
Many are described for hot beverages, and several listings explicitly state they can hold both hot or cold beverages for everyday use.
Several mugs feature printed or etched messages and gift-friendly lettering on the exterior; some pair those messages with interior color-splash details.
