This is a clap stack cymbal. The set includes three cymbals: 11", 13", and 15". By adjusting the tightness of the cymbal tilter nuts, you can create sounds ranging from soft to hard. Although it's a set of three, you can change the sound by altering the order and number of cymbals you stack. This cymbal has a unique resonance, and it creates a good clap sound when mixed with other crash cymbals. It's made overseas and is a no-brand product. There may be scratches from manufacturing or during transportation. https://youtu.be/gQaX600Eyb0?si=EUhkjGNehyAra_Ti
