Very handy very small (2MM wide jaw) grabbers for reading capacitors, etc. that you can't get near with the standard Alligator clips or probes. They accept the same Banana Plug as used on the Blue ESR kit or a double ended Banana lead for voltmeters, etc. They are handy for use around the shop with your voltmeter, etc. able to be secured to IC legs or similar tiny bits of metal so you can take measurements over time more easily.
These are sold by the pair - one red and one black.
These have banana sockets so you can easily change between probes, aligator clips, and Parrot clips!
