I have a collection of boxes if someone needs them. They have been flattened. Two different sizes. i don’t want to set them on a street corner with a free sign as they will become mush.
Very little use as i just moved out to have floors refinished, then moved right back in.
These would also be good to use if you were considering eliminating lawn or weedy areas by sheet mulching (and it’s a good time of year for that).
