Ahlgrens is a former Swedish confectionery company. It was founded by Fredrik Ahlgren in the town of Gävle in 1885 as a store for paint and wallpaper, a business which was later extended to the production and sale of various types of chemicals, perfumes and other products. A mouthwash, introduced in 1908, was given the brandname Läkerol, a year later given to a pastille, which is still sold internationally in several variants.
The product still most closely associated with the brand is 'Ahlgrens bilar' ("Ahlgren's Cars"), sold since 1953 and marketed as "the world's most sold car" (which is possibly technically correct, by number of cars). The small marshmallow cars are so popular within Sweden that stores that specifically cater Swedish tourists and residents in other countries have started selling them as well.
