Unknown product - QR Code only

The image provided focuses solely on a QR code and a small portion of what appears to be an educational workbook or textbook, showing a basic arithmetic problem '7+5'. Because the image lacks any visible brand names, logos, or identifying cover art, it is not possible to determine the specific product name, manufacturer, or company origin.

QR codes on educational materials are commonly used to link to digital resources, audio files, or interactive exercises. Without the context of the book's cover or title page, the ultimate ownership and manufacturing location remain unidentified.
