This gorgeous set is a new set produced by MacKenzie-Childs. It is unmarked, but MacKenzie-Childs shakers are incredibly easy to recognize because most (if not all) have at least some area decorated with a checkerboard type pattern.

The frogs here are colored head to toe in the characteristic black and white checkerboard pattern. Topped off with gold accent on the crown, eyes, and feet.

The set stands about 3'' in height, has 3 and 2 pour holes, and plastic stoppers. Circa 2021.

Below I've included a few other examples of MacKenzie-Childs shakers for comparison.
