Double Wall Insulated Structure for Safe Handling
The double-layer glass design creates an insulating air layer that keeps beverages hot while the outer surface remains cool. This anti-scalding feature improves user safety and comfort, making it ideal for hot coffee, tea, and daily use in both home and café environments.

High Temperature Resistance & Thermal Shock Durability
Made from high-quality borosilicate glass, the cup can withstand high-temperature brewing and sudden temperature changes without cracking. The heat-resistant and explosion-proof performance ensures long-term reliability, which is essential for retail and hospitality applications.

Smooth Rim & Rounded Cup Body Design
The cup features a finely polished smooth rim and a rounded body for a comfortable drinking experience. The ergonomic shape not only enhances grip but also creates a premium, modern appearance that stands out in retail displays and online listings.

Bottom Vent Design for Pressure Balance
A small vent hole at the bottom of the cup helps balance internal pressure between the double layers, improving resistance to temperature changes and preventing glass stress. This structural detail enhances product safety and durability over repeated use.
