Teabloom Oversized Double-Wall Borosilicate Glass Mugs — 17 oz Set of 2, Insulated

These are two oversized 17 oz Teabloom double-wall borosilicate glass mugs that keep drinks hot or cold, showcase blooming teas, and include two complimentary flowering teas.

If you want a visually striking mug that insulates beverages, resists thermal shock, and highlights loose-leaf or blooming teas, this Teabloom set pairs function with presentation. Each tempered borosilicate glass cup features a double-wall design and an air-pressure relief at the base for safer heating and dishwasher use. The package comes with two large mugs and two Teabloom flowering teas to start a ceremony-ready experience right away.

How do these mugs keep my drink hotter or colder for longer?

The double-wall construction creates an insulating pocket of air that slows heat transfer between the drink and the room. This reduces cooling for hot drinks and condensation for chilled beverages, so temperatures remain closer to ideal for longer periods.

• 17 oz volume holds a generous serving without reheating too soon
• Double-wall air barrier reduces heat loss and prevents external condensation
• Thick borosilicate glass resists thermal shock during temperature changes

Are these mugs safe for microwave, dishwasher, and freezer use?

Yes — the Teabloom mugs are designed for everyday versatility. A smart base with an air pressure relief hole reduces stress on the glass during rapid temperature changes and makes microwave and dishwasher use safer when used according to instructions.

• Microwave-safe for reheating beverages briefly
• Dishwasher-safe top rack for easy cleaning
• Freezer-safe for chilling drinks without cracking when cooled gradually

What makes the glass and design durable and elegant?

These mugs are handcrafted from extra-thick borosilicate glass, known for clarity and resistance to thermal shock. The double-wall silhouette gives a floating appearance to your liquid, while the reinforced base protects surfaces and improves balance.

• Ultra-strong borosilicate resists scratching and clouding
• Comfort-grip handles stay cool to the touch
• Double-wall base protects furniture from direct heat

How do these mugs enhance the experience of flowering tea?

The clear, insulated walls provide an unobstructed view of blooming tea blossoms as they unfurl, while the thermal properties maintain a steady steeping temperature. The included Teabloom flowers let you try the visual and flavor effect straight away.

• Crystal clarity highlights colors and movement of flowering teas
• Insulation keeps steeping temperature consistent for fuller infusion
• Two complimentary Teabloom flowering teas are included to start tasting immediately

Who is this for: This set fits tea and coffee lovers who value presentation and practical performance — people who want a larger mug for longer sipping, those who enjoy loose-leaf and blooming teas, and anyone seeking dishwasher- and microwave-safe glassware that looks elegant on the counter or in a serving display. It’s also a thoughtful gift for new homeowners, tea enthusiasts, or anyone building a stylish, functional beverage collection.
