Brew & Sip Anywhere — The Double Wall Glass Tea Bottle

Meet your new favorite companion for loose leaf tea on the go. This elegant double wall borosilicate glass tea bottle combines a built-in stainless steel strainer, protective sleeve, and a clever dual-lid design into one stylish, portable tumbler. Available in 320ml and 420ml sizes, it's perfect for the office desk, morning commute, outdoor adventures, or a relaxed afternoon brew at home.

Key Features

• Double Wall Design: The dual-layer glass construction keeps your hot tea comfortably warm without heating the outer surface, and keeps cold drinks refreshing longer — no sleeves or sleeves of discomfort. Enjoy every sip safely whether you're using boiling water or iced cold brew.
• Built-In Tea Strainer Filter: The stainless steel bottom filter holds loose leaf tea securely so leaves stay out of your drink. The filter allows full infusion for a rich, flavorful cup every time.
• Dual-Lid System: Two removable lids make it easy to load your tea at the bottom, seal in aroma at the top, and fully unscrew both ends for effortless cleaning — no hidden crevices.
• Protective Carry Sleeve: A washable portable sleeve with carrying strap wraps the bottle body to guard against knocks, insulate your hands, and make it easy to carry anywhere — indoors or out.
• Premium Borosilicate Glass: Made from high-grade, BPA-free, lead-free borosilicate glass with strong thermal shock resistance, so sudden temperature changes won't cause cracking. Safe, durable, and built to last.
• Easy to Clean: Wide openings on both ends mean thorough cleaning with a standard bottle brush — no struggling with narrow necks.

Frequently Asked Questions

Q: What sizes does the double wall glass tea bottle come in?

A: The bottle is available in two sizes — 320ml (6.5 × 19 cm) and 420ml (6.5 × 22 cm) — so you can choose the capacity that best fits your daily brewing needs, whether it's a quick cup at the office or a longer outdoor outing.

Q: Is the glass safe for boiling hot water?

A: Yes! The bottle is crafted from high-quality borosilicate glass, which is engineered to withstand thermal shock. You can safely fill it with freshly boiled water without risk of cracking, making it ideal for brewing hot loose leaf tea directly in the bottle.

Q: How do I clean the tea strainer and bottle?

A: The dual-lid design allows you to fully unscrew both the top and bottom lids, giving you complete access to the interior and the stainless steel filter. Both lids and the filter are easy to rinse or clean with a brush. The protective sleeve is also washable for a full, hygienic clean.

Q: Can I use this bottle for cold drinks or fruit infusions?

A: Absolutely. The double wall construction keeps cold beverages at a refreshing temperature, and the stainless steel strainer works equally well for holding fruit pieces or herbs during a cold infusion, making it a versatile bottle for both hot and cold drinks.
