I picked one up because it was torn on the sole of my running shoe.
I keep both of them in my bag and it gives me a strange sense of comfort.
In particular, how did the guy who followed me with the soles of his running shoes think about getting caught in the gap?
Of course, the gap is big, but it fits the size perfectly.
These are stones that I came across by some great coincidence.
It’s amazing, so I’m serving it.
I also clean it sometimes.
