A:AnswerThey appear to be original. I am very happy with them. I guess the only difference is that this package was previously opened. No problems to report.
A:AnswerI *think* but could be wrong that these could be an item that was purchased but not used. Possibly one that a customer purchased and returned. Maybe the box was open preventing the item to be sold as “new”. Refurbished could be that they were checked for function and if any parts were missing and repackaged.
I bought a set and they looked new and function fine.
