Ok, so I got a tin of WoS extra menthol and one honey menthol, and I can see tiny tiny bits of something shiny in there, are they menthol crystals?

probably, I opened a tin of some menthol snuff that had been ‘aging’ for a couple of years and it was loaded with shiny needles of menthol crystals.

It’s natural and definitely not mold. Nothing to worry about my Mentholin has it sometimes too.

Yes ,some aged tobacco will get sugar crystals also.

^ and salt crystals

I’ve seen the shiny crystals too. Esp in Motia snuff. I kinda thought they were menthol crystals. That said, I’ve never seen them in WoS Super Menthol or Hedges.
