We understand your concern that storage could affect the quality of your powder. We can reassure you: both the stand-up pouch and the QJAR are safe storage options when sealed.
Both protect the product from direct sunlight, high temperatures and moisture.
The integrated PE foam insert in the lid absorbs possible moisture and provides an additional protective barrier.
The screw cap with special thread ensures a tight seal and dry storage.
Just make sure to always close the bag or QJAR tightly when not in use. This is the best way to ensure the quality of your product.
