The Stanley Tumbler has a generous capacity of 40 oz (1.18 liters). Its dimensions are 15 cm wide, 11 cm deep, and 28 cm tall, making it a substantial size for staying hydrated throughout the day.

The tumbler is constructed with food-grade stainless steel, using SUS 304 steel for the interior and SUS 202 steel for the exterior. Stainless steel is a safe, durable, and BPA-free material that does not leach toxins into your beverages.

Yes, the tumbler includes a reusable straw for sipping. It features a FlowState screw-on lid that rotates between three positions: a straw opening, a drink spout, and a full-cover top to prevent spills.

Yes, the straw is replaceable if it gets lost or worn out over time. Stanley offers compatible replacement straws that can be purchased separately. Options include:

• Silicone straws: Soft, bendable, and durable. They come in a variety of colors and are easy to clean with a straw brush. Silicone does not heat up like metal straws.
• Stainless steel straws: Rigid and long-lasting. They are made from food-grade stainless steel and can be straight or bent. Some include silicone tips for comfortable sipping.
• Bamboo straws: Eco-friendly and biodegradable. They are made from natural bamboo and provide a unique look. Hand wash and air dry for best durability.
• Glass straws: Elegant and transparent. They are made from tough borosilicate glass and won't impart any flavors. Glass straws are delicate but can last with proper care.

The original Stanley Tumbler straw is made from BPA-free plastic and has a bent design for easy sipping. It is clear in color. Straws typically have a length of 9-10 inches to fit the 40 oz tumbler size. Check the Stanley website or authorized retailers for compatible straw replacements. Mixing and matching straw types can add a fun, personalized touch to your tumbler.

Thanks to its double-wall vacuum insulation, the Stanley Tumbler can keep cold drinks ice cold for up to 24 hours and hot drinks hot for up to 12 hours. This insulation also prevents condensation and sweating on the exterior.

Hand washing is recommended to maintain the quality and insulation of the tumbler. Wash with mild soap and warm water, then dry thoroughly. The straw can be cleaned with a straw brush. Avoid putting it in the dishwasher as high heat may cause damage.

304 stainless steel is used for the interior as it has a higher nickel content (>8%) and chromium content (>18%), making it more resistant to corrosion and suitable for food contact. 202 stainless steel is used for the exterior and provides good durability.

The 40 oz tumbler is designed to fit comfortably in most standard vehicle cup holders. It also includes a rugged handle that makes it convenient to carry around, whether you're commuting, traveling, or heading to the gym.

Stainless steel tumblers are more durable, eco-friendly, and hygienic compared to plastic. They are shatter-resistant, BPA-free, and non-porous, meaning they won't absorb flavors or odors from previous drinks. Stainless steel is also recyclable and sustainable.

Returns are accepted within 7 days of purchase, provided the item is unused and in its original packaging. The tumbler comes with a limited lifetime warranty against manufacturing defects. Contact [email protected] for return, refund, or warranty inquiries.

Yes, many people are indeed looking for sustainable options in their everyday products, including drinkware. The Stanley Tumbler with straw is often considered a sustainable choice for several reasons:

1. Reusability: The Stanley Tumbler is designed for long-term use, reducing the need for single-use plastic bottles or disposable cups.
2. Durable construction: Made from 18/8 stainless steel, these tumblers are built to last, potentially for years, which reduces waste from frequently replacing less durable options.
3. Recycled materials: Some Stanley products, like the Quencher H2.0 FlowState Tumbler, incorporate recycled materials in their construction, further enhancing their eco-friendly appeal.
4. Lifetime warranty: Stanley's "Built for Life" guarantee encourages long-term use and reduces the likelihood of the product ending up in landfills.
5. Promotes hydration: By making it convenient and stylish to carry water, the Stanley Tumbler encourages increased water consumption, potentially reducing reliance on bottled beverages.
6. Energy efficiency: The superior insulation of Stanley Tumblers helps maintain beverage temperature for longer periods, potentially reducing energy use for reheating or cooling drinks.

If sustainability is a priority for you, the Stanley Tumbler with straw could be a good option to consider. However, it's always worth comparing different products and their environmental impacts to find the best fit for your needs and values.
