This is a clap stack cymbal. It's made of B20 alloy and the finish is similar to Istanbul cymbals. The set consists of three cymbals: 9", 11", and 13". By adjusting the tightness of the cymbal tilter nuts, you can achieve 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 stacked. This cymbal has a unique sustain, and it creates a good clap sound when mixed with other crash cymbals. It's made overseas and is a no-brand item. There may be scratches from manufacturing or during transportation. https://youtu.be/xeVska46cZg?si=y3LZkD8ixdux0RZg
