Can I resell my non-used devices anywhere? I have a Next NFC+RFID and an Implantable magnet I don’t need. I want to get a Vivokey Apex. The magnet has never been opened, but the Next has been but it’s needle was never opened. Is there an aftermarket somewhere? I know this may be a silly question but I have had them for years and I don’t know what to do with them. I oher purchased a few years back. Thank you.
