Genuine OE aluminium badges. 79mm (Fits 82mm roundel base - e.g. E39 bonnet roundel).
I bought them to replace the wheel caps on my BBS RSIIs but sold the car. They are the exact size to fit a standard E39 or E46 (and probably a lot of others) front roundel. Or perfect for replacement wheel caps on some BBS wheels (with wide caps).
Paid $50 for the set. Will take $40.
