$70, Brand new.
They install/remove super quick as they are magnetic - just charge them up, clean up the door sill and put these down. Done.
They look really sharp, but one thing to keep in mind is that they don't stop cycling through the different colors. I have asked EV base if there is a way to keep them on one color and they said there is not...

The only catch is that I was sent these to make a video but do not have a model Y. So if you buy these, I will need to make a video of the install, which should not take long at all.
I am in the Naperville, Chicagoland area.
