Conventional Weapons was released as a series of five colored double A-side singles accompanied by digital downloads. Each release was made available for individual purchase, but all five were also offered collectively as part of a limited-edition box set available for pre-order through the official My Chemical Romance online store. The 7-inch vinyl singles were packaged in five different picture sleeves each depicting a different type of weapon. The final single Number Five, was shipped along with a box to house all five individual releases, along with an exclusive poster. All singles were pressed in a different color of vinyl.
