I have these 45 mm stickers left over from my Mazda 3, these are brand new, never used. I do not recall who made them, they're flat epoxy stickers with a carbon fiber look background. I've used similar stickers on my Miata & other cars with no issues for years, although I would hesitate to use these in road salt. I have this type of sticker on the radiator cap of the Miata.
Just $8, I'll ship them in an envelope to the lower 48 for free.
