spring cups

Spring cups are made from a variety of materials, commonly stoneware, polypropylene (plastic), glass, stainless steel, and silicone.

Listings highlight several spill-control features, including spill-proof or leakproof lids, built-in straw stoppers, and low-spill designs. Reviewer feedback often reports reduced leaking or spilling for these features.

Capacities in the results range from 12 ounces up to 40 ounces. Common distinct sizes shown include 12, 15, 16, 18, 24, 30, and 40 ounces.

Some stoneware mugs include traditional handles. Several insulated tumblers are described with ergonomic grips or handles, and larger bottles often feature a bucket-style grab handle.

Several items are labeled BPA-free. One listing notes 20% post-consumer recycled plastic, and at least one bottle is described as free of BPA, lead, and phthalates.
