Keypers were produced by Tonka in the 1980s - hard plastic-bodied adult keypers which came with a key to unlock a special little door somewhere about their body, and softer squishy baby keypers, like the trio you see here, with a slit in their back so you could pop coins and other treasures in them.
Ladybugs, turtles, swans, horses, rabbits, snails…. Keypers came in all shapes and size.
Icons of 1980 toy manufacture.
Useful little compartments for your keepsakes.
And as kitsch as a Barbie Christmas.
