As sustainable reusable drinkware gains growing popularity across global markets, high borosilicate glass cups have become a hot-selling category for tableware wholesalers. Our square high borosilicate glass cup with handle, colorful lid and glass straw is specially developed for bulk export, with stable craftsmanship, wide application scenarios and flexible customization support, helping global importers enrich their drinkware product portfolio and capture consumer demand
Raw material quality determines the service life and safety of glass cups. All our tumblers are produced from food-grade high borosilicate glass material. Thanks to its low thermal expansion coefficient, this material features remarkable thermal shock resistance. The cup can withstand dramatic temperature fluctuation, so customers can pour boiling hot tea and iced fruit juice alternately without worrying about cracking. All finished products pass strict safety testing; the glass contains no lead, cadmium or other hazardous ingredients, complying with EU, US and Southeast Asian food contact regulations. This removes safety compliance barriers for cross-border sales and avoids risks of customs detention
We adopt integrated molding technology for the square cup body. The wall thickness of each glass is evenly controlled to reduce breakage risks during transportation and daily use. The integrated side handle is firmly connected with the cup body, improving structural stability. The matched flip-top lids are equipped with silicone sealing parts to enhance spill resistance. The reserved straw hole fits the supporting glass straw perfectly. Multiple optional color sets for handles, lids and straws allow buyers to assemble different product combinations for target markets. The transparent square outline shows drinks beautifully, which is very suitable for social media promotion, greatly boosting online sales potential
This square glass mug covers extensive consumption scenarios. Ordinary families use it for daily water, milk, tea and homemade beverages. Cafés and dessert shops can use it as specialty drink serving cups. Gift merchants can pack multiple color sets as holiday promotional gifts. Compared with plastic tumblers, glass products deliver higher texture and a premium impression. Unlike ordinary straight glass cups, the handle design solves the scalding problem when holding hot drinks, making it more competitive in the mid-end household goods market. The regular square shape enables tidy stacking, lowering storage and logistics costs for retailers and end users. The non-porous smooth glass surface will not absorb residual smells from fruit, milk or tea, maintaining a fresh taste for every drink
For global wholesale partners, reliable supply chain and personalized solutions are core concerns. Our factory maintains a complete product specification system of square high borosilicate glass cups. Apart from standard models on sale, we provide comprehensive OEM and ODM services.
