This is a case of 1,500 propellers. Propellers are packaged in bags of 10 pcs (150 bags per case)
Perfect for rubber band-powered projects! These propellers are made for projects like rubber band-powered helicopters, propeller planes, and propeller-powered cars 
Fits snugly onto a popsicle / craft stick, or on wood up to 0.135" x 0.35"! Easy for kids and adults to build with, and works every time 
Built-in propeller shaft with small hook for rubber bands! The propellers are designed specifically to be powered by rubber bands. The propeller will only allow you to wind it one way, which ensures that the thrust propels your project the right way 
Generates plenty of lift and thrust! Try using a single rubber band to release energy at a slower rate, or try doubling rubber bands to spend less time winding it up and to get faster burst of energy 
Made with high quality steel and plastic! Semi-flexible plastic is resilient enough to withstand minor to moderate crashes, and the steel will not bend under normal use
