Most listings use plastic or polypropylene; several use silicone; and a few use stainless steel construction.

Capacities in these listings range from about 2 ounces up to 12 ounces. Common sizes include 2 oz, 8 oz, 9 oz, 10 oz and 12 oz.

Several cups include straws or straw features: some list an included straw, some use a weighted straw that moves with the liquid, and others specify leak-proof silicone straws and include straw-cleaning brushes.

Review summaries frequently describe cups as well made and sturdy; many reviewers note good build quality and reasonable durability. Some shoppers mention that prints or seals can fade with extended washing.

Many cups offer handles or contoured shapes to help little hands, including removable side-grip handles, short chunky shapes sized for small hands, slightly weighted bases, and tactile bumps or ridges to stabilize the cup.
