Roylco Jumbo Stencil Set - Gears, Set of 15

Gears are science in motion! These 15 interlocking stencils allow the artist (or engineer!) to fit them together into a mechanical masterpiece. Stencils range in size from 3–9" in diameter. Use the stencils to explore STEM (Science, Technology, Engineering, and Mathematics) concepts in artistic ways, and to help children understand how gears work while they develop fine motor skills.
