The Petal’s disc-shaped film has six exposures, each only 6mm in diameter, which could be enlarged — into ‘petalargements’ — when processed. The camera has a fixed-focus lens.
It was manufactured by St. Peter Optical, primarily for export, and it was distributed in the US by Mycro Camera in 1949. The original circular Petal was followed by the Everax A (engraved with a floral motif) and a slightly larger Sakura Petal octagonal version.
Other smallest-ever analogue cameras include:

- Polaroid iZone 200 — the smallest instant camera
