"Pinky Promise" (pinky swear) This listing is for the Black and White variation. Hard enamel with gold colored metal. This one's for friendship. For lovers, for promises, for secrets, for trust and magic. + Three variations: Black, black/white, and white. + hard enamel + measures 1.75 in (4.3 cm) from across + two pins on the back to stop from spinning + soft rubber pinbacks, which are both more comfortable, and more secure than the old-fashioned metal backers + pin comes on a backing card + uh, it's super cute!! My name is stamped on the back.
