The cup body is made of high borosilicate heat-resistant glass, blown in one piece, unlike cheap ordinary glass on the market. It has strong resistance to temperature differences; even if boiling water is poured directly into an ice cup, it is not likely to crack, making it safer for daily use. The overall clarity is excellent, with very few bubbles or impurities. It's perfect for holding herbal teas, coffees, and fruit drinks, showcasing the original color of the beverage perfectly. Displayed at home or on a store counter, it significantly enhances the visual appeal. The material is resistant to acids and alkalis, so it won't absorb odors even after long-term use with tea and carbonated beverages. It's easy to clean with a simple rinse and doesn't easily leave stubborn tea stains.
Its core anti-scalding design features a double-walled hollow insulation structure. An air gap between the two glass layers prevents heat transfer between the inside and outside. When filled with boiling water, the outer layer remains at room temperature, allowing for comfortable drinking with one hand for extended periods without burns, making it safe for the elderly and children. In summer, when filled with ice water or cold drinks, condensation won't form on the outer wall, eliminating the need for a coaster. Wooden desk surfaces and paper documents will no longer be damaged by water stains, making it exceptionally convenient for office use. The hollow layer also helps to slightly retain heat, slowing down the cooling of hot drinks and preventing iced drinks from quickly reheating, resulting in a better taste when consumed within a short time.
The selection of styles caters to various needs. Straight-sided cups and egg-shaped cups without handles are suitable for making lattes and sparkling water in cafes; mugs with handles are more convenient for brewing tea in the office and for everyday drinking; and there are also models with bamboo or silicone lids to prevent spills when traveling. With a variety of capacity options, the 200ml small size is perfect for afternoon tea or espresso; the 300ml to 350ml size is a universally flattering size; and the 450ml large size is suitable for daily drinking and sharing among multiple people. The rim is polished and smooth, preventing irritation to the lips when drinking. The seamless, one-piece design eliminates any hard-to-reach areas for dirt and grime, making it dishwasher safe.
Why choose a double-walled glass cup
Physical heat protection: The double-walled hollow structure blocks heat conduction. Even if the internal water temperature reaches 100℃, the outer wall remains warm to the touch, protecting your hands from burns.
Condensation prevention: When pouring iced drinks, the double-walled structure effectively prevents condensation from forming on the cup walls, avoiding wetting your desk or documents.
High-end aesthetics and transparency: Compared to plastic and ceramic cups, glass is easier to clean and odorless, and its crystal-clear texture offers a modern aesthetic.
This glass cup is suitable for a wide range of applications, including daily drinking water, brewing herbal teas, and pour-over coffee at home; commercial use in chain coffee shops, dessert shops, and Western restaurants; standard water cups for hotel and guesthouse rooms; corporate holiday gifts and exhibition souvenir sets; and best-selling items in the home furnishing and gift categories for cross-border e-commerce. We can handle both small sample orders and large-volume orders (full containers). Regular in-stock styles ship quickly, while production cycles for special shapes and customized capacities can be negotiated.
Compared to plastic and stainless steel water cups, glass does not retain strange odors, making it healthier to drink from. Compared to single-walled glass cups, its advantages of being heat-resistant and preventing water droplets are difficult to replace. Objectively speaking, glass is susceptible to breakage from strong impacts, so for high-frequency commercial use, thickened outer packaging can be used to reduce damage during transportation and use. Whether for domestic home furnishing wholesalers, catering suppliers, or overseas trading companies, this heat-resistant double-walled glass water cup combines safety, heat resistance, practicality, and aesthetics, suitable for most drinking water usage scenarios, and is a consistently high-volume, essential product in the tableware category.
