Matchbox Two Packs (stylized as "Two" Packs) originated in 1976. They featured two vehicles in a single box or blister pack. Some vehicles were the same as those then available in the 1-75 range, while others were special editions. Once the 1-75 range split into INT and USA versions, "Two" Packs sometimes featured vehicles from the other line, e.g. an INT vehicle in the USA market. Sets were numbered with a TP- prefix under all series names. For 1983, the series was renamed Twin Packs. Numbering featured three digits for 1984.
