Check the listing for details. Five 5 fiber optic probes (image illumination) [endoscopic 1 m light reflection]. Condition: Used. Listed at 84.99 USD. These are five fiber optic cables. I have no way of properly testing them. They look like they were used, or at least have shelf wear. I'm not sure what type of cable they are, but I think they are a "reflection" type cable used for endoscopy? There are only two words on them, "Image" and Illumination". The "Illumination" end appears to have three strands of fiber optic in it and the "Image" end appears to have one. They are about 1 meter long. Three of the cables have rigid, silver colored rods on the end. The other two have flexible, copper colored ends. The "Image" end on two of the silver rod ones do not appear to light up like the others. All the other ends light up when pointed at a bright light source. That's the best I can do as far as testing. I can't guarantee they are working correctly. The price is for all five.
