VANCKEY Double Wall: Double wall design- ensures that the cup comes into contact with hot drinks and does not condense with cold drinks. It also keeps your drinks hot or cold longer than a layered glass under the same conditions. Stylish Appearance: Double walls and clear body- creates a floating illusion that makes your drinks more attractive. A perfect choice for coffee, tea, desserts and more. A great addition to any table and event. Borosilicate Glass: Adopting superior borosilicate glass, the cup is made lighter-clearer and high temperature explosive proof. And it allows you to instantly pour boiling water into a frozen mug. Great Gift Choice: It is a nice gift for any occasion - birthday, anniversary, housewarming, engagement or wedding.
