Orafol (founded in 1991) is a global company headquartered in Oranienburg, Brandenburg, Germany. Its core business areas are graphic products, self-adhesive reflective films, industrial adhesive tapes, and plastic products. In addition to the headquarters, there are additional production facilities and sales offices in Europe (Thuringia, Great Britain, Ireland), North America (USA, Canada), Turkey, South Africa, Asia (Japan, China, Taiwan, India), and Australia. You can usually only buy the Oramask 810 and Oramask 813 on rolls. Sheets of film are usually pre-cut by the retailer or wholesaler, which then sells for considerably more. Since film is hard to come by in roll form here in Europe at a reasonable price (1 roll 30 cm wide x 5 m long = €50), I tried other films as well. The Kabuki films from model making suppliers worked very well. The Tamiya sheets also worked. Cricut Smart Stencil also works. All in all, I have to say that film in roll form is significantly cheaper than in sheet form, even though some retailers think that they have to charge much more for everything when there are supply shortages. That's why you should prefer the roll form and cut it yourself. Just be careful, the film also ages and deteriorates over time – so don't buy too much! Have fun building your model! Harry
