reuse cup

Reusable cups and tumblers in this set are made from glass, several types of plastic, silicone or polypropylene, and stainless steel (including 18/8 stainless steel in some insulated mugs).

Capacities shown range from small toddler cups around 7–10 ounces up to large insulated tumblers of about 30–40 ounces; some glass tumblers are listed at roughly 12.5–16.75 fl oz.

Common lid types include flip‑top lids and straw lids. Straw features include weighted or removable straws, straws that peel open for cleaning, one‑way valves for spill control, and many cups include a matching straw and/or lid.

Cold retention varies by model, but insulated tumblers in this set report extended performance—examples include ranges like 9 hours cold and up to 40 hours iced. Actual results depend on the specific product and usage conditions.

Some stainless steel tumblers are labeled suitable for both hot and cold beverages. Glass tumblers in this set are noted as not for use with hot liquids.

Features include leakproof or spillproof lids, one‑way valve or silicone straw valves to control flow, flip‑top lids with click‑lock or similar leak‑resistant closures, and silicone valves on training cups for spill control.

Many insulated tumblers are designed to fit standard cup holders; product details in this set note general cup‑holder compatibility and at least one listing specifies a car cup holder–compatible base diameter of 3.15 inches.
