Kodak ceased sales of standard 8 mm film under its own brand in the early 1990s, but continued to manufacture the film, which was sold via independent film stores. Black-and-white 8 mm film is still manufactured in the Czech Republic, and several companies buy bulk quantities of 16 mm film to make regular 8 mm by re-perforating the stock, cutting it into 25 foot (7.6 m) lengths, and collecting it into special standard 8 mm spools, which they then sell. Re-perforation requires special equipment. Some specialists also produce Super 8 mm film from existing 16 mm, or even 35 mm film stock.
