Fuguang Glass Cup for Men And Women, Office Double-Layer Large Capacity Water Bottle with Handle, Tea Infuser Mug with Tea Strainer

Double-layer plastic and glass cup with inner glass liner and outer PC plastic shell structure, details can be seen in the product description and diagram on the details page (plastic and glass cups cannot be disassembled by yourself).

The plastic shell of the glass cup provides a certain level of heat resistance and anti-drop effect compared to conventional single-layer glass cups. For those who prioritize heat insulation, consider our double-layer glass or insulated products. For those who prioritize durability, check out our insulated products.

All glass cups, regardless of structure (single-layer, double-layer, plastic and glass), do not have heat preservation properties unless they have a mercury layer on the inner wall. For heat preservation, we recommend purchasing our insulated products.

The plastic shell has been tested for heat resistance (at around 25°C room temperature) and provides a certain level of heat insulation compared to single-layer glass material.

The plastic shell maintains a safe temperature range for human touch when pouring 80°C hot water for a certain period of time.

The glass cup is made of high borosilicate glass, which can withstand sudden temperature changes from -20°C to 100°C without cracking.

The combination of glass inner liner and plastic outer shell provides durability and resistance to impact.

The cup features a separate tea compartment for filtering tea leaves and adjusting tea strength, along with a 316 stainless steel filter for a clean tea experience.
