Elevate your daily hydration experience with our 20 OZ Stainless Steel Tumbler—where durability, functionality, and natural charm converge. Designed to keep your favorite beverages at the perfect temperature year-round, this tumbler pairs reliable performance with a stunning nature-themed design, making it a versatile companion for home, work, travel, or outdoor getaways.
1. Exterior & Dimensions
The tumbler boasts a smooth matte white finish that resists fingerprints and minor scratches, ensuring a fresh, clean look even with daily use. Its standout feature is the meticulously crafted nature-themed pattern—printed with non-toxic, fade-resistant ink, the design showcases serene elements like lush green ferns, delicate wildflowers, winding tree branches, and soft moss textures. This nature-inspired aesthetic brings a touch of calm to your routine, whether you’re sipping coffee at your desk or water on a hike.
In terms of size, the tumbler maintains practical dimensions: 21.2 cm in height and 7.3 cm in diameter (width), offering a comfortable, ergonomic grip that fits most standard cup holders—from car cup holders to office desk organizers. It also includes two essential accessories: a 23 cm food-grade stainless steel straw (ideal for iced drinks, smoothies, or iced coffee) and a soft-bristle cleaning brush (specifically shaped to reach the inside of the straw, ensuring hassle-free, thorough cleaning after each use).
2. Material & Safety
Consistent with our commitment to quality and safety, every component of the tumbler is carefully selected:
- Tumbler Body: Constructed from 18/8 food-grade stainless steel (304 stainless steel), a rust-resistant, corrosion-proof material that is 100% free from BPA, phthalates, and toxic chemicals. This ensures no metallic aftertaste transfers to your drinks, keeping them pure and flavorful.
- Lid: Equipped with a leak-proof, BPA-free plastic lid featuring a flexible silicone seal. The seal creates a tight barrier to prevent spills, even when the tumbler is tilted or placed in a bag. The lid also has a convenient flip-top opening for easy straw access, and it’s designed to be easy to disassemble for deep cleaning.
- Straw & Brush: The stainless steel straw matches the tumbler’s body material (18/8 stainless steel) for consistency and safety, while the cleaning brush has a sturdy plastic handle and soft nylon bristles—gentle enough to avoid scratching the straw’s interior, yet effective at removing residue.
3. Insulation Performance
Built with double-wall vacuum insulation technology, this tumbler delivers exceptional temperature retention, making it suitable for all seasons:
- Hot Drinks: Keeps coffee, tea, hot cocoa, or even soup warm for up to 12 hours, maintaining temperatures between 140°F–160°F (60°C–71°C) so you can savor a hot sip hours after pouring.
- Cold Drinks: Preserves iced water, iced tea, smoothies, or soda cold for up to 24 hours, holding temperatures between 32°F–45°F (0°C–7°C) even on warm days.
The vacuum-sealed gap between the two stainless steel walls also eliminates exterior condensation—no more wet hands or water stains on your bag, desk, or car seats.
4. Weight & Portability
Despite its heavy-duty insulation and durable build, the tumbler remains lightweight and easy to carry:
- Empty Weight: Approximately 350 grams (12.3 ounces)—light enough to hold in one hand during your commute, carry on a walk, or stow in a backpack without adding unnecessary bulk.
- Full Weight (with 20 OZ Liquid): Around 950 grams (33.5 ounces)—still manageable for all-day use, whether you’re heading to the gym, running errands, or going on a weekend camping trip.
5. Usage & Care Tips
- Dishwasher Safety: The tumbler body and stainless steel straw are safe for top-rack dishwasher cleaning. To protect the lid’s silicone seal and extend its lifespan, we recommend hand-washing the lid with warm, soapy water.
- Microwave Warning: Do not place the tumbler or straw in the microwave—stainless steel can cause sparks and damage the appliance, and it will not heat drinks evenly.
- Freezing Warning: Avoid freezing the tumbler, as extreme cold can compromise the vacuum seal and reduce its insulation performance over time.
