Description

These interlocking gear stencils put the STEAM in STEM. A series of 15 gears represent round, square and oval gears in many sizes. The stencils are made of durable, see-through blue plastic to allow the artist (or engineer) to fit the gears together as they create a mechanical masterpiece. Interior teeth on several gear stencils increase the options and add interest. Includes 15 stencils ranging from 9 in to 3 in and a guide.
