These are a good size. They are easy to write on. From there it is a bit down hill. The black indelible marker is only legible for about 60 days. It lasts longer on other brands. Every one of them rotted off at the soil line and fell off before the end of the season. I put them in in 2020 the weekend after Easter and they broke off under their own weight around the 1st week in September. I went back to the other brand I was using.
