Teabloom Cosmopolitan 16oz Stainless Steel Travel Tumbler — Slim Insulated Bottle with Two-Way Tea/Coffee Filter (Rose Gold)

The Teabloom Cosmopolitan is a 16oz stainless-steel, all-beverage travel tumbler that brews tea, cold brew, infused water and keeps drinks hot or cold for hours.

Designed as an all-in-one reusable flask, the Cosmopolitan blends a tea infuser, fine two-way stainless-steel filter, and double-wall insulation into a slim, car-cup-holder-friendly bottle. Lightweight yet durable, it resists stains, odors and corrosion while delivering a cleaner brew thanks to a .5mm filter mesh. Shown often in gift guides and featured in Oprah's magazine, this tumbler is built for daily use at home, the office, workouts, and travel.

How does the Cosmopolitan handle tea, coffee and fruit-infused water?

The Cosmopolitan’s two-way stainless-steel filter is designed to accommodate loose-leaf tea, cold-brew coffee and fruit infusions without clogging or letting large particles through. You can steep directly in the flask or use the filter to pour a finished brew while trapping leaves and pulp.

• Two-way filter with .5mm holes for finer separation and smoother pours.
• Use for hot steeping, cold-brewing, or fruit-infused water without swapping parts.
• Removable filter allows easy rinsing to switch beverages quickly.

Will my drink stay hot or cold, and how portable is it?

The double-wall vacuum insulation keeps hot drinks warm and cold ones chilled for extended periods, while the slim 16oz (480ml) body fits most car cup holders and backpack pockets. The brushed metallic exterior stays comfortable to hold without condensation.

• 16oz capacity balances portability with enough volume for most daily drinks.
• Slim design fits standard cup holders and small bag pockets.
• Exterior resists condensation, making it comfortable to carry and set down.

How easy is cleaning and maintenance?

The Cosmopolitan is built for low-maintenance everyday use: the stainless-steel interior resists stains and odors, and the filter and lid disassemble for hand-washing. Regular rinsing after use prevents flavor transfer when switching beverages.

• Removable stainless filter and lid for thorough cleaning by hand.
• Interior material resists staining and lingering smells.
• Dishwasher not recommended—hand wash to protect finishes and seals.

What color and style options are available?

Available in a selection of polished finishes to suit personal style or gifting, the Cosmopolitan comes in Rose Gold, Navy Blue, Ruby Red, Jet Black, and Pearl White. Each color has the same brushed metallic exterior and refined silhouette.

• Choice of five colors to match daily carry or coordinate as a gift.
• Brushed metallic finish for an upscale look that hides light wear.
• Packaged for gifting with a premium presentation box.

Who is this for? The Teabloom Cosmopolitan is ideal for someone who wants one reliable bottle that handles loose-leaf tea, cold-brew coffee, and infused water without extra accessories. It's a practical upgrade for commuters, frequent travelers, office workers, gym-goers, and anyone who prefers reusable drinkware over disposables. If you want a versatile, easy-to-clean, and stylish flask that reduces single-use waste while delivering a refined brew, the Cosmopolitan fits the bill.
