Double Wall Glass Espresso Cup Set of 4, 3 Oz Insulated Mugs

This set of four double walled espresso cups combines practical insulation with refined visibility for daily coffee service. Built around a thickened borosilica base, these insulated shot glasses preserve optimal drinking temperatures while showcasing layered brews and espresso finishes.

• Capacity and Quantity: Arrives as a complete set of four matching tumblers, each holding exactly three ounces of liquid.
• Double Wall Insulation: Uses paired glass layers separated by an air gap that blocks external heat transfer and prevents cold conduction to your grip.
• Thickened Build: Engineered at a fifty percent greater wall thickness than typical drinkware to improve stability and extend daily lifespan.
• Borosilicate Material: Formed from completely lead-free silica designed to resist fracturing when exposed to rapid temperature fluctuations.
• Microwave Compatibility: Supports direct reheating on standard settings to quickly restore preferred beverage warmth.
• High Clarity Finish: Offers flawless transparency that reveals crema textures, milk emulsions, or dark roast tones.
• Hand-Blown Contour: Features organic shaping that creates a floating visual effect, where the inner liquid appears suspended inside the outer shell.
• Low-Maintenance Surface: Polished interiors resist residue buildup and rinse cleanly after routine washing cycles.

The insulated architecture keeps hands comfortable whether pouring steaming morning drip or serving chilled afternoon tea, removing the need for extra cooling pads or protective sleeves. The crystal-clear silhouette turns routine machine outputs into visually precise pours that look intentional on kitchen counters or café service areas. Durable silica construction tolerates repeated heating cycles while simplifying cleanup, allowing you to maintain steady pacing and consistent temperatures throughout daily use.
