Design

The aesthetic is defined by a contemporary "Dual" double-wall profile, featuring two layers of crystal-clear European glass that create a striking optical illusion of a floating beverage. This mouth-blown construction includes a unique rim where the two walls meld into a single layer, offering a sleek, minimalist look that eliminates outer condensation and prevents messy water rings on your furniture.

Durability

Built from laboratory-grade 3.3 borosilicate glass, these tumblers are engineered to handle extreme temperature fluctuations ranging from $-40\text{°C}$ to $+300\text{°C}$. This specialized material is highly resistant to thermal shock and chemical erosion, ensuring the glass remains clear and structurally sound even when transitioning between icy storage and boiling liquids.

Care

The non-porous surface is naturally hygienic, lead-free, and cadmium-free, ensuring it will never absorb odors or leach chemicals into your drinks. While these glasses are fully dishwasher safe for easy cleanup, it is recommended to wash them with gentle detergents and avoid abrasive pads; always follow the principle of gradual cooling to maintain the integrity of the vacuum seal.

Versatility & Safety

This eco-friendly set is microwave and freezer safe, making it ideal for everything from reheating a morning latte to serving chilled desserts. The thermal insulation acts as a protective barrier, keeping hot coffee at its peak temperature for longer while keeping the exterior cool to the touch, and it is equally effective at maintaining the crispness of iced tea without the glass "sweating."
