Refill Bag Storage & Usage Guidelines

  • Before Opening (Sealed): Store the unopened, sealed bag in a cool, dry place at room temperature. Avoid direct sunlight, high temperatures, and humidity to maintain material stability.
  • After Opening: Once the sealed packaging is opened, we recommend using the refill bag within 3 months to prevent changes in material properties that may affect performance.
  • Long-Term Storage: If the unopened refill bag has been stored for more than 1 year, inspect it carefully before use. Check that the packaging is intact and that the material shows no signs of change. Use only if everything appears normal.
  • Important: Do not store the refill bag in high temperatures, direct sunlight, or humid environments. Do not use if the packaging is damaged or the material appears abnormal.
