The insignia for Futari wa Pretty Cure and its sequel includes a basic icon of a heart with two curves and a crown-looking part that flips upside down. This insignia is seen on almost every item, such as the Cures' pouches for their Card Communes or Heartful Communes. The shape of the insignia resembles the shape of the Prism Hopish, one of the most important items in Futari wa Pretty Cure.

The insignia can also be spotted in the beginning of their Nagisa and Honoka'stransformation in Futari wa Pretty Cure Max Heart. It appears in golden color right before their clothes start to appear.

In Max Heart, the Heartful Communes feature a different emblem that resembles the original, but with a flipped heart beneath the top one.
