Do not expose empty containers to direct sunlight, flame roasting, or microwave heating
It can damage the vacuum insulation layer of the cup, causing the thermal insulation to fail and even lead to deformation or damage.
Don’t fill the boiling water too full
Overfilling with hot water can cause spills and burns, while prolonged immersion of the cup lid’s rubber ring may accelerate its aging and lead to leaks.
Do not use steel wool or hard brushes to clean the interior
It can damage the inner lining’s protective layer, leading to rust and dirt accumulation over time.
Do not store in water for extended periods
Prolonged water accumulation in the cup without drying can easily lead to bacterial growth
