As its name implies, the Mailer Lock is used primarily for mailing sample products. The closure is designed to be secure and to withstand substantial abuse without malfunctioning. This style of carton is usually assembled, filled and sealed manually. The lock tab (tongue) provides additional security, ensuring that the carton does not inadvertently open in transit.
