I know this is comparing apples to oranges but I had a beard balm that had granules of beeswax in it. It felt very grainy/sandy. You had to rub it a lot in your hands to get it to heat up and melt. It also didn’t absorb and left a layer of ‘skin.’ Hence my dislike and eventual binning of an almost full tin.
If you rub the Seville in your hands and heat it do the grains disappear? Chances are you’re right and it’s just old or a bad batch.
I’ll try it in the morning and see if that works.
I also have the Le Grand Chypre balm from B&M and it works great so I’m almost positive there is something wrong with this balm. I messaged Will at B&M to see what he says about it.
