What a fun classic novelty! It's fun to share with younger friends who might never have seen such things. Interpret your romantic mood (fickle, in love, jealous, ...)
Simply lay the wafer-thin plastic fish right in the palm of your hand. Your body temperature will make the fish curl, flip and squirm.
Each of these little fellows comes in his own sleeve with the instructions on the fish and interpretation on the back of the sleeve.
