CAT.5E FLAT CABLE ROHS The above was written on the inside of the cable. I don't know what kind of cable it is, and I'm giving it away because I'm not using it. It has been stored at home for a long time. To avoid any problems, please refrain from purchasing if you are looking for a perfect item like those in a store or if you are overly concerned about minor details. I would like to give it to someone who understands the condition.
