Just measured a variety of different ones I have, sizes as follows, left to right:

0.79mm, 0.80mm, 0.73mm, 0.86mm, 0.79mm, 0.77mm & 0.79mm all taken at the tip and none are Omega or 'branded'

Thanks very much for that.

Would say .8
Based on what I have seen and bought over the years.

there are three sizes, no need to measure.

too big
too small
it fits
And also the Irish Spring Bars that shrink with use but they smell so good…

I’ve looked at the OEM Omega tips compared to a known .9, and I think they look very close in diameter. Though not measured.
