Where to get replacement metal number plates?

[kael-el]

I pick up my new M3 RWD in a couple of weeks. Once I get my V5, I want to put my personalised plates on the car. I know that Tesla use the thin metal style plates, so they fit in the (ugly) holder. I'm not looking to get rid of the holder (I would only put a new plate on wonky), but does anyone know where I can order some thin metal ones from? (Ideally with the new green strip also)
I believe number1plates used to do them, but they have gone into liquidation...
Thanks

I had Tesla make up extra plates for both of our Teslas. With our Model 3 they were free of charge (back in August 2019). This year in June for our Model Y they charged £30. Just for a point of reference.

I used Halfords for mine, complete with green strip. They're metal, and the holder conveniently covers up the Halfords text at the bottom of the plate.

Great, thank you both!
