Please read the description carefully. Quinke V.1 Aluminum RCA Cam 4.0mm FK Irons Cartridge Grip Both purchased last October. Used until last year, but I'm selling them because I switched to wireless this year. All items are sterilized. No individual sales. Please make your judgment based on the photos as these are used items. Also, I will immediately report to the administration any excessive price reduction requests, overly sensitive individuals, those who do not read the description, or those who neglect communication regarding returns, and will take screenshots as evidence. I strive to make transactions as pleasant as possible. Thank you.
