These are cheap decoy foam drones with less electronics. The amount of fuel decides how far they fly. Favorable wind? They fly further.
They are cheap but the rockets to shoot them down cost (I've heard but don't count on it) around $480,000 per missile. That is not a minor consideration for a country like Romania.

Is this true for non-decoy non-foam drones and basically everything else that flies, even things with solid boosters? Seems like a strange part to add here as it basically applies to aviation in general, replace "fuel" with "stored energy" and literally all type of "vehicle" fits basically.
