These are first and second row WeatherTech floor mats. Original price was $201.90 (not counting shipping and tax). They have been very lightly used for less than a year and look like new.
While I am not sure, these may also fit other model year Kia Niro EVs.
The front two might fit a regular gas-powered Niro. The back mat will not because it doesn't have enough rubber in the middle to go over the transmission hump while keeping the sides in place.
I am willing to mail these, but will need to charge for mailing costs.
