A set of like new Black rapid straps, both the Curve and the Wrist strap along with a FR-3 fastener that screws into a camera's tripod socket.

This strap attaches to the tripod mount instead of the standard strap holders, they allow a camera to be worn sling style at your side and be able to slide up to eye level to take a picture easily. They are designed primarily for DSLR cameras.

The wrist strap offers a more compact option to secure the camera.

I'm selling both for $50, they list for over $80 total, price is somewhat flexible. I only used them once or twice.
