This 5 pack of foam boomerangs are for use only in light to no wind environments. If thrown during a windy day they will not be heavy enough to withstand even moderate wind currents. They are ideal for use in a gymnasium or an area where the wind can be controlled. The Kiwi miniboom is made of extremely light foam material which makes them safe even for small children but they still need to be thrown correctly to get them to work. See our instructions! ** Right-Handed Only **
