These tabs help to securely seal the tube, preventing the toothpaste from drying out or leaking.
The design ensures that the toothpaste remains fresh and hygienic for use over an extended period.
In addition, the presence of tabs makes the pack more user-friendly, as it allows for easy opening and closing, while maintaining the integrity of the product inside.
This feature adds to the convenience and practicality of the packaging, making option (C) the most suitable choice for a functional and well-designed toothpaste pack.
