This isn?t just any foam ? it?s our specially engineered ?memorang? foam, which can be ?tuned? for different flight paths. It?s perfect for throwing around larger rooms or even in the garden ? as long as it?s not too windy! When thrown as instructed, it will travel in a 4-6 metre circle and return to the spot ? guaranteed!
