CNGLASS 12oz Double Wall Glass Coffee Mugs Set of 2 — Clear Borosilicate, Insulated with Handle

These CNGLASS 12oz double-wall glass coffee mugs are insulated, heat-safe drinking glasses with handles designed to keep beverages hot or cold while protecting your hands.

Enjoy your espresso, latte, cappuccino or tea in lightweight, hand-blown borosilicate glass that resists thermal shock and looks crystal clear on the table. Each set contains two 12-ounce clear mugs with an integrated handle and a double-wall cavity that reduces heat transfer. They arrive in an elegant box, are dishwasher- and microwave-friendly, and are made without lead or BPA for everyday use.

How does the double-wall design affect temperature and handling?

The two-layer glass traps a thin air pocket between inner and outer walls, slowing heat loss from hot drinks and condensation with cold ones. That means your drink stays closer to its serving temperature longer while the outer surface remains comfortable to hold.

• Insulating air gap reduces heat transfer and exterior warmth.
• Less condensation when serving iced beverages.
• Comfortable to hold without additional sleeves or coasters.

What materials and safety features are built into these mugs?

Made from borosilicate glass, these cups are lighter than standard glass yet more resistant to thermal shock and breakage. The formulation is free of lead and BPA, and the shape and finish are designed for daily kitchen use.

• Hand-blown borosilicate glass for lightweight durability.
• 100% lead-free and BPA-free construction.
• Wide opening and smooth rim for easy drinking and cleaning.

Are these CNGLASS mugs practical for everyday use and cleaning?

Yes—these mugs are compatible with microwave and dishwasher routines, and their wide bore makes rinsing and hand-washing straightforward. While oven-safe for some uses, avoid metal utensils that could scratch the glass and follow care instructions to extend lifespan.

• Dishwasher-safe on top rack for convenient cleaning.
• Microwave-safe for reheating; avoid sudden temperature shocks.
