An integrated product mailing system comprises a product to be mailed and a mailer enclosure secured to the product for enclosing and mailing the product once the product is spent. In a preferred embodiment, a toner cartridge for a laser printer includes a cavity disposed in the cartridge, a mailer enclosure disposed in the cavity, and means for removably securing the mailer enclosure in the cavity, whereby the mailer enclosure may be removed from the cavity to be used for easily and efficiently surrounding, enclosing and mailing the product. The mailer enclosure is folded, compacted, or deflated in the cavity, and unfolded upon use for enclosing the product. An access cover secures the mailer in the cavity, and the cavity is integrated into the cartridge for functional efficiency and aesthetic presence of the cartridge and mailer combination.
