Common materials include ceramic, borosilicate glass, regular glass, 18/8 stainless steel (often with silicone sleeves), and polypropylene plastic.
Sets often advertise space-saving, stackable designs. Features include cups that nest into each other, cups that stack on or into a matching carafe, and some sets that come with a metal rack or holder to neatly store nested cups and saucers.
Capacities vary from small espresso sizes (around 3 oz) up to large carafes (about 33.81 oz). Common single-glass sizes include 5 oz, 7 oz, 8 oz, 10 oz, 12.6 oz, and 13.5 fl oz.
Product details list suggested ages such as “0–6 Years” for some stainless steel cups and “3 Years and Up” for several plastic tumbler sets.
