 The Lundström brothers had obtained a sample of red phosphorus matches from Arthur Albright at The Great Exhibition, but had misplaced it and therefore they did not try the matches until just before the Paris Exhibition of 1855 when they found that the matches were still usable.In 1858 their company produced around 12 million matchboxes.The safety of "true" "safety matches" is derived from the separation of the reactive ingredients between a match head on the end of a paraffin-impregnated splint and the special striking surface (in addition to the safety aspect of replacing the white phosphorus with red phosphorus).
