By design, there is a divider in the middle which threw off my planting plan a bit but I think it's needed there for stability. These are a really thick high quality plastic and the green is darker and nicer looking than the picture shows. I have them placed over a metal railing outside of my high rise condo. They fit perfectly and the stabilizers at the back are a really nice touch, especially with them being in a place that gets such high winds.  Very happy with the purchase!
