This is a spiral cymbal. It can be used alone or stacked. The B8 spiral is characterized by its powerful sound. When used stacked with other crash cymbals, etc., it can produce a more gritty sound than a regular stack cymbal. As this is an imported cymbal, there may be scratches or stains from manufacturing or shipping.
