These are pretty much like new. I have used them a couple of times. I have listed the approx. C4 sizing next to each. These are lighter, and the heads are smaller than C4s, allowing them to be placed in more pods. I am selling them because I don't use them. 

$40 per cam + buyer pays shipping or $220 for all 6. All have racking biners as well!
