I found this today near a block of flats, around the halfway point of my circuit. I didn’t really want to take it because it was big and once it went into my trolley, nothing else would fit. So I decided to leave it and make my rounds first. After that, I came back to pick it up.
I have a very specific use for storage boxes like this. I use 2 every month, but I find more than 2 every month. I’m running out of space to store my storage boxes.
