Introduced in the 1960s, Treets came in three varieties – peanut (yellow bag), toffee (pale blue bag) and chocolate (brown bag). They were near-spherical chocolate/nut/toffee lumps “sealed in a crispy shell”.
The magic of Treets was that they could be stored in the inside pocket of your suit without any risk of stains – hence their slogan “Melt in your mouth, not in your hand”.
They were ousted by M&Ms and Minstrels in the 1980s and discontinued in 1988.
