12oz Stainless Steel Tumbler with Lid and Straw - Insulated 6 Pack

In this review of the 12oz stainless steel tumbler set, the bottom line is simple: these cups are best for buyers who want a compact, durable everyday tumbler that keeps drinks hot or cold for hours while fitting most car cup holders. The reviewer found the set practical for kids, commuters, and small-drink users because the 12 oz size is easy to handle and the double wall insulation reliably preserves temperature. The inclusion of lids and reusable straws makes them convenient for travel and parties without adding a metallic taste to beverages.

Key Features

• 304 18/8 stainless steel: Provides a food-safe interior so drinks taste pure and free of metallic aftertaste.
• Double wall vacuum insulation: Keeps liquids hot for up to about three hours and cold for up to nine hours under normal conditions, helping maintain beverage temperature on the go.
• Includes lid and straw: Each tumbler ships with a plastic lid and reusable straw for spill-reduced sipping and convenient use while traveling.
• Colored powder coat finish: A stylish outer coating resists sweat and stays cool to the touch with hot beverages, improving grip and appearance.
• Compact 12 oz size: With a height of 5.11 in and a lid diameter of 3.38 in, the cups fit most car cup holders and are easy for small hands to handle.

Who It's For

These tumblers are ideal for parents buying a small, insulated cup for toddlers, commuters who prefer a modest 12 oz coffee portion, or anyone attending events who wants a durable reusable cup in bulk. The set format and compact dimensions make them suitable for gifting, party favors, or short road trips where a smaller beverage volume is preferred.

Shoppers who need very long-term heat retention for multi-day trips, or who require a wider mouth for loose-leaf tea or full-size bottles, should look elsewhere. Also, if an ultra-durable lid is a top priority for heavy daily abuse, be aware some customers reported lid durability concerns and may prefer models with reinforced locking lids.
