Designed by DJI to perfectly fit the Spark's propellers, these DJI Prop Guards can help reduce the risk of damage or injury from spinning props. They will also protect the props themselves from the impact of a collision with a hard, flat surface.  The DJI Prop Guards are compact, lightweight, easy to mount and easy to detach.

NOTE: Each guard can only be mounted to its matching arm - each one is different.
