CNGLASS Double-Wall Thermo Glass Coffee Cups 13.5 oz Set of 4 — Clear Borosilicate, Insulated, Microwave & Dishwasher Safe

The CNGLASS 13.5 oz double-wall thermo glass coffee cup is a set of four clear, insulated borosilicate mugs designed to keep beverages hot or cold while protecting your hands from heat.

These hand-blown borosilicate glasses combine a modern transparent look with practical thermal insulation. Each 13.5 oz mug features a double-wall construction that traps temperature and prevents condensation, making them suitable for lattes, cappuccinos, tea, milk drinks and iced beverages. Lightweight yet durable, the set arrives in an elegant gift box and is rated for everyday use in the microwave, dishwasher and freezer.

How does the double-wall design protect my hands and the drink?

The dual-chamber glass creates an insulating barrier between the liquid and the outer surface. Hot beverages stay warm longer while the exterior remains comfortable to hold; cold drinks won’t sweat or leave rings on surfaces.

• 13.5 oz capacity per mug — good for standard lattes and large coffees.
• Insulation minimizes heat transfer to the outside surface.
• Reduces condensation with cold drinks, keeping tables clean.
• Clear walls showcase layered drinks like lattes and cappuccinos.

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

Yes — the CNGLASS cups are made from heat-resistant borosilicate glass that tolerates temperature changes better than ordinary glass. You can reheat in the microwave, chill drinks in the freezer and clean them in the dishwasher without special care, though hand washing will extend longevity.

• Borosilicate material resists thermal shock compared with standard glass.
• Microwave-safe for quick reheats of coffee or milk-based drinks.
• Dishwasher-safe for convenient cleaning; top-rack recommended.
• Freezer-safe for chilled beverages or prep of iced drinks.

What makes these glasses durable and healthy for daily use?

Hand-blown borosilicate glass offers greater strength at thinner walls, delivering a lightweight cup that still withstands everyday use. The material is 100% lead-free and BPA-free, meeting common expectations for safe drinkware.

• Hand-blown construction for uniform thickness and an elegant silhouette.
