The Leaf Cards are typically for use with the Botany Cabinet, but can be used separately as well. The set consists of two sets of twenty-four cards (forty-eight cards in all). Each set shows the shape of a different leaf type in either a thin outline or as a solid shape. A compartmentalized storage box is also included. The cards measure 14 cm square and the box is 16 cm x 11.5 cm.
