CPL-10BW - Greenwich Coupling with wide loop for NEM Sockets

This is the standard Greenwich Coupling for 4mm. It consists of a 3D printed shank that plugs directly into an NEM socket and a wider brass etched loop that needs cutting out, folding up and blackening.

Included is the iron wire needed to make them uncouple when moved over a magnet.

The pack contains enough parts for 5 pairs of couplings.
