All-in-one personal tea cup with built-in tea strainer for unique tea tasting experience. Made of high quality borosilicate glass can withstand high and low temperatures. Known for its heat resistance and physical durability, borosilicate glass is useful in many applications mostly involved with temperature changes. The material owes its strength and resistance to its unique combination of silica, boric oxide, among various other oxides. The presence of boron oxide to replace some of the oxide components enhances the binding forces within the glass material. Compared to similar glassware, borosilicate glass can withstand blunt force impact better.
