metal drinking cup

Most metal drinking cups are made from stainless steel—commonly food-grade 18/8 stainless steel. Some listings note recycled 18/8 stainless steel, and many cups use BPA-free lids or parts.

Capacities range from small cup sizes up to large hydration tumblers. Common sizes shown include about 11 oz and 16 fl oz on the small end, and larger options such as 24 oz, 30 oz, 32 fl oz, and 40 oz.

Warranty coverage varies by model. Examples in the listings include a 6‑month limited warranty, a 1‑year limited warranty, and lifetime or limited lifetime warranties.

Many metal drinking cups use double-wall vacuum insulation. Reported temperature retention varies by model: hot retention is often a few hours (an example listing cites about 3 hours), while cold/iced retention ranges broadly in listings from roughly 8 hours up to around 40+ hours, with some entries noting about 24 hours for cold drinks.

Anti‑spill features commonly include leak‑proof or sealing lids, locking or push‑button locks on the lid, multi‑position or rotating covers that seal openings, and straw designs that secure the straw to reduce spills.

Options include built‑in or reusable straw lids, drink‑thru or flip‑top spouts, and “sip‑or‑swig” designs that let you sip through a straw or tilt back to drink from a wide mouth. Some lids combine multiple drinking modes in one design.
