【MICROWAVE, FREEZER & DISHWASHER SAFE】Microwave Heating: It is important to note that the lid of our container is designed for airtight sealing. We strongly recommend opening the vents or removing the lid when heating food in the microwave. This allows for proper ventilation and prevents pressure buildup.

When using the oven for extended periods, it is advisable to completely remove the lid, as prolonged high temperatures may cause deformation of the silicone sealing strip on the lid edge. 【HANDWASH the lid to preserve its quality】The soft, flexible silicone ring is designed for a secure seal and can be easily removed for cleaning.

To reinstall, gently press the silicone strip into the groove to ensure a perfect fit. Avoid pushing it, as this may prevent proper alignment with the grooves.
