What are the causes of ink leakage?

Bumpy transportation and air pressure factors will inevitably cause ink leakage when opening the lid or tearing the label.

In some areas, the altitude is too high, resulting in inconsistent air pressure inside and outside the ink cartridge, which may lead to leakage ink. Let the item sit for a while before use. To avoid damage, it is recommended to wrap the cartridge with a tissue before opening the lid or tearing the label.
