Feel free to take them.

When I walk down the street in Tokyo, I sometimes come across these
things: the daily use items and hobby goods lined up in front of the entrance with a board that says "ご自由にお持ちください。(feel free to take them)".

It's a great Japanese custom to cherish things and not waste them.
I didn’t take anything this time, but it's interesting that I can roughly
imagine what kind of person they are by looking at the items.
