The production date of Berek products will be marked on the product packaging, and you can directly check the packaging to get this information. In addition, the date of production is not clearly marked on the package. You can check the IMEI code of the product on Berek's official website, or you can scan the QR code on the package with APP, so you can also check the production date.

To ensure the accuracy, you can contact Berek's customer service directly, and you will be able to provide the information you want. If you already have the product and can't determine the production date, you can also consider contacting the after-sales department for consultation.
