Capacities range from small toddler cups (about 7–10 ounces) to insulated tumblers commonly offered in sizes such as 14, 30, and 40 ounces.
Toddler and small cold cups are typically made from plastic, while insulated tumblers are made from stainless steel — often specified as food‑grade 18/8 stainless steel (including recycled 18/8 in some listings).
Common accessories include reusable straws and spare lids; some toddler cups also include cleaning tools like a straw brush, and a few insulated mugs mention extra silicone or stainless straws.
Smaller straw cups are typically marketed for infants and toddlers, with suggested ages commonly listed as 6 months and up or 12 months and up, depending on the product.
Some toddler straw cups are built with as few as three parts (cup, lid, straw) and include features—like a straw that peels open—designed to make disassembly and cleaning easier.
