When you receive the product, there will be two dates displayed at the bottom of the packaging box: the Production Batch Number and the Production Date. Production Batch Number "Production Batch Number" is a unique identification code assigned by the manufacturer to a batch of products produced at the same time, location and using the same process. This code can be used to differentiate between different batches of products and identify them during subsequent management, tracing and quality control processes. It allows for the tracking of specific batches to understand their production history and other relevant information. Production Date Since our product has a shelf life of 18 months, you don't need to worry when you see these two dates. Please feel free to use it with confidence.
