High-Quality Material: Made of high-quality borosilicate glass, which is a special glass material with high temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. The cup will not break even at high temperatures. All glassware is fragile, so handle and wash it carefully.<br>Unique Appearance: Simple and smooth lines, crystal-clear glass, very beautiful when placed on the dining table. The double-insulated walls and transparent body create an illusion of floating, making your drinks more attractive. Perfect for coffee, latte, espresso, cappuccino, tea, and hot or cold drinks.<br>Double-Walled Design: Features an insulated double-walled design to keep your drinks hot longer. This design allows the cup to hold hot drinks safely and prevent condensation when storing cold drinks. Your drink will stay hot or cold longer than a single-walled glass under the same conditions.
