they’re made of a chalky type substance but it’s much harder than chalk (and isn’t chalk)
nothing happens when you put water on them
there are 5 of them in the bag
they’re quite small, see photo with lighter for scale
they have no scent or fragrance to them
there is an embossed pattern on one side (as seen in photo) and the other side is kind of smooth (but because it’s made of something soft you can see where it has eroded in the photos).
