Excellent used condition! Light marks, no cracks or keyholing.
 
From Zildjian:
 
Slightly heavier than the Dark Crash Thins, the K Dark Crash Medium Thins are dark and warm, with stronger high-end crash qualities. Crashes emit a lower pitch, land with more body. They have a clearer and louder bell sound, and feature stronger cut and projection for an even bolder K sound.
