If you know, you know.  Black Diamond C4 cams are legendary.  Their ease of use and excellent size range rarely leaves you wanting more.

All of these cams have been well used and loved.  One of the #2's should probable be reslung, otherwise I would for sure whip on the rest.
Color matching BD Nutrino's.  When Elvis leg takes ahold, don't panic, one look down and you know exactly what to grab.

Looking to sell as a set for $500 shipped
I will hold out for at least a few days before I decide to break it up.
