110 is essentially a miniaturized version of Kodak's earlier 126 film format. Each frame is 13 mm × 17 mm (0.51 in × 0.67 in), with one registration hole. The 110 cartridge was introduced by Kodak in 1972 and discontinued manufacturing slide film in 1982 and all 110 cameras in 1994. Fujifilm stopped manufacturing 110 format film in September 2009. Lomography re-commenced 110 film production in 2011 and it is still producing it today in 2020. Cartridges with 12, 20, or 24 frames are available on-line. Production variations sometimes have allowed for an additional image.
