A mailing carton of the type having end air pockets is strengthened at each end by edges formed by multiple layers of corrugated material extending outwardly from the interior compartment and also by reinforced layers of corrugated material forming an end wall inwardly from the reinforced edges. A recess formed in the center of each multiple layered top edge facilitates utilization of an "L" shaped sealing tool for sealing the end walls of the top panel by short reinforced adhesive tape segments disposed on surfaces in right angular relationship.
