You receive 2 propellers: one prop rotates clockwise cw and the other prop rotates counter clockwise ccw (1 left hand & 1 right hand rotation). These matched rotor blades are a hard to find matched counter rotating pair. The length is 10 inches and the pitch is 4.5 inches per revolution.
This pack includes two propeller blades with adapters (1 CW and 1 CCW), similar to the photo displayed (color might be different)
