A booster is a single Beyblade X top you extend your collection with. This box belongs to an assortment: which model is inside is not fixed in advance. The one pictured is the Horn Rhino 3-80S, a defense type, but that can differ from box to box.
There is only a top inside. To play you also need a launcher and a Beystadium, and the box states in so many words that they are sold separately. Anyone who already plays Beyblade X usually has them lying around.
Every Beyblade X top is built up from three layers: the blade, the ratchet and the bit. You take them apart and combine them with parts from other tops, so you can look for a set-up of your own that stands up to attacks. The box is marked 8+.
An affordable addition for someone who already has a launcher and an arena: fine as a small present, or to build out a collection step by step.
