Listings show mugs made from ceramic and glass — specifically borosilicate glass and other glass types.

Listed capacities include 11 oz, 5.4 oz, 12 oz, 20 oz, 0.15 oz, 13.5 oz, and 5 oz. (Values are as provided in the listings and may vary or be rounded by sellers.)

Several glass mugs use double-wall or thermal insulation (often borosilicate) to help keep drinks hot or cold longer; descriptions also note temperature resistance.

Results include single mugs and multi-piece sets with Number of Pieces shown as 1, 2, 4, and 6.

Double-wall borosilicate glass is described as keeping drinks hot while the outside stays cool and preventing condensation rings; some listings also include specific temperature-resistance ranges.
