Smarties are colour-varied sugar-coated chocolate confectionery. They have been manufactured since 1937,[1] originally by H.I. Rowntree & Company in the United Kingdom, and now by Nestlé.Smarties are oblate spheroids with a minor axis of about 5 mm (0.2 in) and a major axis of about 12 mm (0.5 in). They come in eight colours: red, orange, yellow, green, blue, mauve,[2] pink and brown, although the blue variety was temporarily replaced by a white variety in some countries, while an alternative natural colouring dye of the blue colour was being researched.[3] [Wikipedia]
