Spangles
Square boiled sweets in a paper tube, including the notorious Old English.
The sweet everyone over forty brings up unprompted. Discontinued in 1984, briefly revived, and mourned ever since.
Spangles came in a paper wrapper twisted at both ends, and the sweets were square with rounded corners and a dimple in the middle. Fruit flavours, mints, and the legendary Old English, which tasted like a Victorian chemist.
They are the standard reference point for British sweet nostalgia. Mention them anywhere and somebody will tell you about the Old English within thirty seconds.
