An improved mailer set is proposed which makes for easier removal of the interior plies therefrom. The position of the thumb notches along the opposite edges of the mailer set, which in the past were located directly across from one another, have been relocated in an offset manner. This enables the opposing pressure needed to burst apart the mailer set to be reduced since the plurality of perforate lines are burst sequentially rather than simultaneously. |
