Opal Mints started off with a spearmint leaf motif on the wrappers as a purely white minty alternative to Opal Fruits (with lots of ice-oriented TV advertising). Then along came a name change and then three green spearmint stripes.
The adverts for the new look Pacer featured the old trusty people in white on ice skates suddenly being hit by green, at which point their t-shirts became green and white striped. Tasted like a tube of Colgate toothpaste dissolved in a swimming pool.
The Celtic football team were nicknamed “The Pacers” at one point because of the similarity of their kit to the sweets.
The brand was discontinued in the 1980s.
