💡 Care & Usage Instructions

Temperature Guidelines

• This product is made of non-heat-resistant glass. Do not use with water over 50°C, hot drinks, or boiling water.
• The allowable temperature difference between the water and the external environment is generally ≤30°C.
• The 50°C threshold is difficult to control, so we strongly advise against using the product for hot drinks.

Prohibited Equipment

• Do not use microwave, dishwasher, oven, disinfection cabinet, or open flame.
• Dishwashers use high-pressure water and detergents that may cause a chemical reaction, leaving a white haze that dulls the glass.

Cleaning

• To prevent damage, clean separately with warm water and non-abrasive cleaning supplies.
• Gently wash by hand and avoid using hard tools that may scratch the surface.

Fragility Notice

• This is non-tempered glass, so avoid impact to prevent breakage.

Handmade Characteristics

• Slight variations in pattern, color, and minor handcraft traces (e.g., tiny bubbles, water marks) are normal artistic features—not defects.
