Usually in places like Whole Foods or Sprouts, the larger type healthy grocery store set ups that have hygiene products. I actually get/got mine at a super high end foofoo grocery store, every city has these ridiculously high end grocery stores we avoid because you need a Range Rover or BMW to park in the lot. These stores usually sell a whole range of bath and body products you don't find in the normal grocers.

I actually started using them because my pit sticks would melt in the heat of my car, sitting in my bag all day. The crystal is just a rock sized...well crystal rock looking object you get a little wet and apply like you normally would. No scent but you don't have a scent either.
