CNGLASS 17oz Double-Walled Glass Coffee Mugs with Handle — Set of 4, Insulated Borosilicate, Dishwasher & Microwave Safe

These CNGLASS 17oz double-walled glass mugs keep hot drinks warm and hands cool while presenting beverages in a crystal-clear, elegant way.

Designed for everyday coffee, tea and specialty drinks, this set of four borosilicate-glass cups combines thermal insulation, a comfortable handle and dishwasher/microwave compatibility. Each cup is hand-blown for lightweight strength and clarity, giving you the look of fine glass with practical durability. The double-wall construction traps heat to slow cooling and prevents condensation with cold drinks, so tabletops stay clean and hands stay comfortable.

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

The two layers of borosilicate glass create an insulating air pocket, which reduces heat transfer from the hot liquid to the outer surface. That means you can hold a near-boiling beverage without burning your fingers and your drink stays warmer longer than in single-wall glass.

• Insulating air gap reduces surface heat and maintains beverage temperature.
• Outer glass stays cool to the touch for safe handling.
• Works for both hot and iced beverages—no exterior sweating.

Are these mugs durable and safe for everyday use?

Yes — they are crafted from borosilicate glass, which is lighter and more thermal-shock resistant than ordinary glass. The material is free of lead and BPA and the cups are designed to withstand typical kitchen use with minimal risk of damage.

• Hand-blown borosilicate glass for strength and clarity.
• 100% lead-free and BPA-free for food safety.
• Engineered for everyday handling but treat with normal glassware care.

Can I use these mugs in the microwave, dishwasher or freezer?

These CNGLASS mugs are suitable for microwave heating, dishwasher cleanup and short-term freezer storage when used sensibly. Borosilicate glass tolerates wide temperature ranges, but avoid abrupt extreme temperature changes (for example, moving directly from freezer to microwave) to prevent stress.

• Microwave-safe for reheating coffee or milk-based drinks.
• Dishwasher-safe for convenient cleaning; use top rack if desired.
• Freezer-safe for chillers and iced drinks if cooled gradually.

What makes this set a good gift or kitchen upgrade?

The clean, clear silhouette showcases latte layers, colorful teas and cocktails, making each pour look professionally presented. The set includes four matching mugs with handles, packaged neatly for gifting or for refreshing your own drinkware collection.

• Clear glass highlights crema, froth and layered beverages.
• Set of four is ideal for couples, small households, or entertaining guests.
• Attractive packaging makes it ready for gifting occasions.

Who is this set for? These CNGLASS 17oz double-walled mugs suit coffee lovers, tea drinkers, home baristas and anyone who wants elegant, practical drinkware. They are especially useful for people who appreciate clear presentation of layered drinks, need thermal insulation without bulky materials, or want dishwasher- and microwave-compatible glass that still looks refined on the table.
