SHANDERBAR 12oz Double-Walled Glass Coffee Mugs Set of 4 — Clear Borosilicate with Handles, Insulated

These SHANDERBAR 12oz double-walled borosilicate glass mugs with handles keep drinks at the right temperature while creating a floating, elegant presentation.

Designed for everyday use at home, the office or a small café, this set of four clear 12oz glass coffee mugs pairs lightweight durability with thermal insulation. Each cup is hand-blown from borosilicate glass so it tolerates wide temperature ranges, resists thermal shock when used responsibly, and showcases beverages with a clean, modern double-wall profile. The ergonomic handle and smooth rim make each sip comfortable while the transparent walls highlight layers, crema, and ice without condensation dampening surfaces.

How do these mugs protect hot and cold drinks?

The double-wall construction creates an insulating air gap that slows heat transfer and limits condensation on cold drinks. That keeps hot beverages comfortable to hold and cold drinks from leaving rings on tabletops.

• 12oz (350ml) capacity for standard coffees and lattes
• Double-wall air cavity reduces heat loss and surface condensation
• Small pressure-equalizing vent in the outer layer prevents stress during temperature changes

Are these SHANDERBAR glasses durable and safe for daily use?

Made from 100% borosilicate glass, the mugs are lighter than many alternatives and resist cracking from normal thermal changes when handled correctly. They are suited for microwave use and refrigeration, though care is advised to avoid sudden, extreme temperature shocks.

• Hand-blown borosilicate glass for strength and lightness
• Temperature range suitable for hot and cold beverages (-4°F to 302°F)
• Dishwasher safe, with handwashing recommended to extend lifespan

How should I care for and clean these double-walled cups?

The smooth glass surface cleans easily with warm water and mild detergent; while dishwasher use is acceptable, gentle handwashing preserves clarity and seal integrity. Avoid immersing the base vent directly or soaking long periods to prevent water entry into the pressure-equalizing hole.

• Prefer mild soap and a soft cloth or sponge for best results
• Avoid rapid submersion of piping-hot mugs into cold water
• Do not rinse the vent hole directly or soak long-term to prevent water ingress

What occasions and beverages suit this set best?

These clear insulated mugs are versatile for daily coffee, tea, lattes and iced drinks, and present layered or specialty beverages attractively. The set-of-four format makes them practical for couples, small households, or as an elegant gift for celebrations.

• Ideal for lattes, cappuccinos, iced coffee, tea, and hot chocolate
• Thoughtful present for housewarmings, weddings, and holidays
• Compact 12oz size fits most coffee machines and drink routines
