5-Piece Set High Borosilicate Glass Jar with Lid Kitchen Storage

Our core series of glass cups are made of food-grade high borosilicate glass, while our regular series adopt food-grade soda-lime glass. All products fully comply with national safety standards for food contact materials, featuring lead-free, cadmium-free, odor-free properties and no hazardous substance precipitation. They can be safely used for holding drinking water, various beverages and food.

Pure glass bodies without metal accessories (including gold rims, metal lids, and metal handles) are safe for use in microwave ovens, dishwashers and disinfection cabinets. For models with metal decorations or accessories, they must NOT be placed in microwave ovens, and hand washing is recommended to prevent wear and oxidation of the metal parts.

Glass is inherently a fragile material. Our full product line features a thickened cup body and reinforced cup bottom, which greatly improves daily impact resistance. Nevertheless, severe impact and falling from high places should be avoided. We also offer shatter-resistant models with silicone protective sleeves for further reduction of breakage risks.

We provide a full range of customization services, including corporate procurement customization, personalized engraving, and exclusive logo or pattern printing. Relevant design documents are required for customization. The standard production lead time is 7-15 working days, subject to the customization process and order quantity. Please contact our customer service for detailed consultation on specific requirements.

Accurate parameters including full cup capacity, cup body height, caliber, and bottom diameter are clearly marked on the detail page of each product. A certain capacity error and a size error within 5% may exist due to manual measurement, which falls within the normal process tolerance range of glass products and will not affect normal use.
