Given this metal’s legendary difficulty in fabrication we’d all but given up hope of seeing it in a small footprint bar. In fact, we now have officially given up hope for a 1-gram offering. At least one that would make any sense. The thinnest bar in a 15x8mm format like the rest of the bars on this page that can be made - at least using the current techniques measures about 2mm in thickness and weighs 2.5 grams.

These very popular little bars now come with mirror polishing by default. Get in on the action while osmium is still (relatively) affordable!
