These are the remaining copper wires I purchased for practice for the 2025 electrician's exam. Approximately enough for two uses, including VVF 1.6 and 2.0 from HOZAN's second-class electrical engineer training materials. Since they were used for practice, they may have scratches and very small pieces. I tried to remove them, but there might be some coating residue. My measurement is 2330g, but please allow for some error. I apologize, but please refrain from price negotiations.
