The Zildjian FX Promo Pack contains cymbals produced by the famous Zildjian secret process that has been handed down from generation to generation, and were hand picked from the Zildjian Vault. This pack contains a durable 6" bell for piercing accents, a laser-cut 16" EFX crash for bright, rapid and dirty tones and an 18" FX Oriental China cymbal to take out the trash. These are the same superior cast bronze cymbals played by the world's best drummers.
