An e-liquid cartridge designed to provide e-liquid for an electronic cigarette vaporizer, the cartridge including two apertures, the first aperture being used to fill the cartridge on a filing line and then being covered with a bung or plug or other form of seal and the second aperture being sealed by a septum or other form of seal that is designed to be penetrated or punctured by a needle or stem that, in use, withdraws e-liquid from the cartridge. The first aperture is sized to enable rapid filling with e-liquid on an automated or semi-automated manufacturing line.
