SRP-design four-valve box with 1 gluing point for shampoo. Printing is made on a white top liner board using 2 colors.
To display products on the shelf, it is enough only to separate two parts of the cardboard along the zip-perforation line. For easier opening and handling, the box is provided with a perforated line for a finger. After pressing it, we get a hole through which the box is transformed into a tray.
During packing of the product, upper and lower valves are fixed with glue or tape.
